Advanced industrial lasers have evolved well beyond simple cutting and welding applications. Laser technology now offers an industrial de-coating and surface cleaning solution that is cost effective as well as responsive to environmental concerns. From the automated cleaning of molds to precise de-coating to oxide removal, laser surface treatments are proving to be an attractive option to traditional labor-intensive methods.
In the past decade laser paint removal and cleaning systems have generated significant interest as a viable alternative to conventional cleaning and paint removal technologies.fiber laser marking machine Research on mobile, reliable, and powerful laser systems for cleaning and paint removal operations began in the late 1980s with the modification of welding or cutting lasers into laser systems for surface preparation. This approach did not meet the requirements for surface preparation, which are significantly different than for cutting and welding.

In the early 1990s, research took place around the world for more efficient, reliable laser systems for surface preparation work. It took another few years to develop the technology from experimental laboratory systems to dependable systems capable of use in day-to-day industrial operations. Today, a wide variety of industries have adopted laser systems for a range of surface preparation tasks. Applications include mold cleaning, paint removal, joining pretreatment, oil and grease removal, and many more.
Operating principle
The laser generates a directed and monochromatic beam of light which typically is tightly focused to create high power density. At the focal point, the energy of the intense laser beam will be absorbed by the contamination or paint layer, thermally incinerating or sublimating the target material, such as paint or contamination (see FIGURE 1). These processes will, in combination with the resulting micro-thermal shockwave,fiber laser marking machine remove the target material as long as the target material is able to absorb the incident laser energy. The better the target material absorbs the energy, the faster it can be removed.
Color, chemical composition, and thickness of the target layer all have a direct impact on the effectiveness of the process. The removal process automatically stops once a metal, or otherwise relatively reflective, substrate is reached.
Reflective surfaces do not generally readily absorb the laser energy.
Any residual heat transfer into the substrate material can be a critical factor.
To minimize this effect, many laser equipment manufacturers use pulsed laser sources. The beam intensity (laser power per beam spot) is a critical parameter for the heat transfer into the substrate material. Very short laser pulses with a pulse duration of only a few nanoseconds (ns) in combination with a very small focus diameter (0.02 in) or longer pulses in the millisecond (ms) range with a larger focus diameter (0.2 in) result in a minimal heat transfer into the substrate material. Under normal operating conditions and with the right process parameters, damage to the substrate material can be avoided.
The heat transfer factor of continuous-wave laser systems is much higher and might result in substrate temperatures that will damage the substrate. Test results with a handheld pulsed Nd:YAG laser with an average laser power of 500W (peak power of more than 400kW) on an aircraft aluminum sheet resulted in maximum substrate temperatures of 170 °F.
Pulsed laser systems generate laser power levels well beyond the average power of the laser source.fiber laser marking machine A pulsed 150W solid-state laser will generate a peak pulse power of more than 160kW. This high peak power and the above mentioned beam parameter result in a power intensity removing many target materials with acceptable production rates.
Currently, there are three different kinds of laser sources available for
surface preparation works. The main difference is the laser beam generation and the resulting beam delivery configuration.

Development of laser technology range is beyond what we can imagine. Nanosecond laser, the microchip laser, and us to the femtosecond laser had made great contributions to the cause of science and medicine. But a special laser stand out, it's fiber laser.

In the past couple of years,the production of this top class laser has increased by up to 300% annually, which gives testament to their efficiency compared to the likes of Carbon dioxide lasers, which are predominantly less effective. fiber laser marking systems The fiber laser has proven invaluable in folding metals, welding and cutting backing a potent punch in its high optical contact beam that gives a clean, precise cut with the slightest of efforts. This fiber laser is coming at the very opportune time. Many large scale industries are now becoming aware of the need for effective lasers, and that is trickling down to improved production and overall growth in terms of operational capacity.

The fiber laser is a technological milestone-one that will cause a revolution in the manufacturing industry and bring the kind of value that has been lacking over the years. When you think about the kind of versatility you get with this laser, coupled to the fact that it has substantially lesser carbon dioxide emissions; then what you get is a solid state laser that is both effective and environmentally friendly, which is more than can be said for its competitors.

Fiber lasers are tipped to be a major contributor to technological growth in the very near future, and they are expected to change many industries for the better.fiber laser marking systems The adoption of solid state laser is also set to replace other less effective lasers, and to benefit many different sectors both in business and other relevant industries.
New technology is beginning to shift the proverbial posts, and to redefine our approach to emerging trends. Fiber lasers are a promising new investment, both as an eco-friendly tool, and an impressive industrial innovation.

Although, there are a number laser marking machines available of in the market, the latest state-of-the-art technology used widely is the fiber laser machine.
This machine is the best option existing that uses fiber-pumping technology to “dope” fibers with a unique earthy element like Ytterbium.

Using this element (Ytterbium) in a laser marking machine increases the ability of fibers to carry high-emitting diodes, which are pumped to optical heads through the fibers. fiber laser marking systems At this point, the light beam expands to produce the capability of laser marking. The light beam is then able to mark a variety of materials using any one of the following four methods:

1. Removal of a layer of any material or Ablation
2. Etching of material surface to change color or Carbon Migration
3. Bonding
4. Laser Engraving

Laser marking applications are suitable with a several material types. These can range from leather to plastics and metals as well. The different kind of metals that fit perfectly to the fiber laser engraving criteria include silver, bronze, gold, stainless steel and platinum. Other materials and elements that respond positively to fiber laser marking include copper, aluminum, carbide, tungsten and medical grade alloys.

Different Ways That Laser Marking Machines can be used
A fiber laser marking machine that uses fiber lasers is also known as a laser engraving machine due to the resulting surface patterns produced during the ablation process.  fiber laser marking systemsThe laser machines are used for an array of applications including:Jewelry Engraving,Laser Cutting and Medical Devices& Equipment

A laser marking system includes a high power fiber laser with a double clad fiber having a doped core surrounded by an inner pump cladding and providing an optical output for marking; a high power laser diode source for pumping the double clad fiber laser via an input into the inner pump cladding; an optical scanner coupled to receive the marking output from the double clad fiber laser to scan the output over a surface of an article to be marked by sweeping the marking output in one, two or three dimensions to form strokes, the completion of which comprises indicia to be marked on the article surface; and a controller to control the operation of the scanner synchronized with the modulation of the laser diode pump source to initiate the marking output and sweep  fiber laser marking systems and modulate the marking optical output in one, two or three dimensions to form strokes comprising the indicia. A main advantage of the fiber laser marking system over CO2 and YAG laser marking systems is the ability to provide modulation via the semiconductor laser diode at the input to the marking laser rather than having to modulate the optical power beam at the output of the marking laser, such as through an acusto-optic modulator, which provides for a pulse of non-uniform stability across the pulse width with a substantial decrease in the amount of power in the modulated beam output. Also disclosed is circuitry to dampen the ON-time rise of a current signal input for operation of the laser diode pump source to improve the ON-time quality of the marking optical output created by the double clad fiber marking laser.
FIELD OF THE INVENTION
This invention relates generally to a laser marking system and more particularly to fiber laser marking systems operated cw or pulsed for marking surfaces of objects with information or data, hereinafter referred to as “indicia” which includes, for example, alphanumeric information, letters, words, personal or company logos, tradenames, trademarks, data or batch codes, numbers, symbols, patterns, article coding or identification, personalized signatures, and the like.

BACKGROUND OF THE INVENTION
Laser marking systems have been in existence as early as 1971 for marking indicia on surfaces of articles. fiber laser marking systems A major use of laser marking of articles is for marking an article or product or a product package particularly with respect to high volume manufacturing lines, so as to take advantage of marking these goods “on-the-fly”. This type of marking provides data about the product, such as, date of manufacture, shelf life, factory origin, model and/or serial number, product tracking and the like. The use of lasers to provide marking indicia is preferred since it does not generally affect the integrity of the article or product or its packaging and the marked indicia is not easily removable.

The concept of using visible light for marking and engraving of substrates took the industrial world by storm.
Originally called an optical maser back in 1958, the first functioning laser was invented a few years later. Since then, multiple applications have been found for the use of lasers, and research continues into ways to achieve ongoing improvements. The modern fiber-based laser marking machines are advanced compared with the flash lamp and diode-based laser markers of years past.

Older Laser Marking Methods
First Generation flash lamp laser marking machines comprised a section of gas-filled glass tubing, which generated short bursts of intense white light. Although the systems are stable, easy to install and cost effective to operate,fiber laser marking machine they require an external water chiller to control the heat. The diode-based solid state laser markers can be used for most purposes and use an in-built chiller, but requires a temperature-controlled environment to operate effectively.
Although these laser marking systems work well and have long life spans, their replacement with more modern equipment has a multitude of benefits.

Fiber Laser Marking Technology
The latest development in laser marking machines is the fiber-based laser marker. Using up-to-date fiber pumping technology, the laser markers use optic fibers bundled together and impregnated with a substance that increases their conductivity. The fibers are pumped with light-emitting diodes, and the light of the laser passes through to the optical head, from where the beam is expanded to create the laser mark. This method produces a much higher quality beam than the first generation laser marking machines were capable of, with reduced volatility and cost.

Fiber Laser Marking Benefits
Air cooling eliminates the need for the water chiller; the laser marking system uses no consumables and requires minimal maintenance. The diodes have a lifetime of more than 50,000-80,000 hours, and the small footprint of the fiber-based laser marking machines makes it possible to install them easily in almost any location. These reliable
laser marking systems are environmentally friendly,fiber laser marking machine using no harsh chemicals or high temperatures during the process and safely delivering high quality, permanent laser marking on metals, stainless steel, ceramics and plastics.

The fiber laser marking process is becoming increasingly popular for numerous uses. Its high temperature resistance makes it perfect for marking medical equipment that requires sterilization, such as surgical devices. The durability of the laser marks optimizes it for use in jewelry, mobile phones, and other items of value. The 21st century laser marking software that operates the laser marking machines generates detailed, high quality images for faultless
identification.

The use of laser marking has increased over the past two decades, mainly due to its popularity as a labeling medium.
Its use carries substantive advantages in identifying product inventories and the ability to provide consumer information on products. The wide range of materials that can be marked using this method also makes it extremely flexible for commercial and industrial purposes.fiber laser marking machine For optimal results, choose a fiber laser marking machine for your business.
How Does Laser Marking Work?

Several types of laser marking machines exist, but the most up-to-date technology available is that of the fiber laser. This kind of laser machine, widely considered to be the best option in existence, uses fiber pumping technology to “dope” the fibers with a rare-earth element such as Ytterbium.

The use of this element increases the ability of the fibers to conduct light-emitting diodes, which are then pumped through the fibers to the optical heads. At that point, the beam of light expands to create the laser marking capability. The beam of light then marks the material using one of four methods:

Laser engraving
Ablation or removal of a layer of the material Carbon migration or etching of the surface of the material to change the color Bonding
You can use fiber laser marking on a wide range of materials, from different types of metal through to leather and plastics. Types of metals that lend themselves well to fiber laser engraving include platinum, stainless steel, silver, gold and bronze.fiber laser marking machine Carbide, tungsten, copper, aluminum or medical-grade alloys also respond well to fiber laser marking.

Ways to Use Laser Marking

Fiber laser marking, which is also known as laser engraving because of the resulting surface pattern produced by the ablation process, is used for a variety of applications including:

Medical Devices and Equipment – surgical devices and other medical products that require frequent sterilization (often at high temperatures) use identification marks that can withstand the cleansing process without interfering with the health of the patient.

Jewelry Engraving – creation of unique marks to identify or brand items of jewelry has become popular for copyright protection and recovery of stolen property. The precision of laser engraving is also used to personalize pieces such as wedding bands with the vows or the couple’s marriage date.

Laser Cutting - light laser cutting is also very popular in the jewelry industry. Light metals are used to create name cutouts and monograms as well as other design cut outs.

Computerized parts such as printed circuit boards use laser marking to produce clear, high-resolution images that are ink- and acid-free for use in electronic applications.

If you’re in the business of manufacturing or selling any of these types of products,fiber laser marking machine then fiber laser marking equipment is the one you need. This is just a small sampling of the many applications that fiber laser markers are being used for.

With so many different types of material combined with such a wide range of laser types and technologies, finding the right laser for your marking application can be a bit of a minefield. Here are five critical areas you should focus on before making your decision.

Laser Power
On paper, power determines the speed of laser marking. Some materials simply won’t mark on too low a power. If throughput is a priority, other issues come into play.fiber laser marking systems             For instance, the spot size increasing and causing a loss of resolution.Laser marking car partsFactors such M² (beam quality) and spot size create their own complications. The spot size is determined by lens configuration and expansion matrix. The bigger the spot size, the lower the energy density per mm sq. So power is spread over a wider area. The result is that a 10W laser could have a higher energy density per mm sq. simply because of the optical set-up than a laser with a higher power.Peak energy also needs to be considered as manufacturers mainly quote CW (Continuous Wave) power. This does not take into account peak energy. As an example, a 10W Vanadate laser will have a higher peak energy than a 10W fibre laser but the fibre laser will be cheaper to run.At the end of the day, it all depends on your applications.

Mark Field Size
Yet again it is your application requirement that dictates. Most manufacturers offer a 100mm sq. marking window as standard. TLM offer 290 mm sq. as standard and 560mm sq. for special applications. There is, as ever, a trade-off. As the mark field increases, so does the spot size. So a more powerful laser may be needed to cope with a larger field size.

Applications, Service and Support
To ensure your laser operates efficiently and with optimum productivity, it is essential you have access to reliable
technical support. TLM has many years’ experience in working with the laser service industry. With nationwide cover, our team of highly trained engineers are never more than 2-3 hours from you.
