Why Are Fiber Laser Marking Machines Better Compared With Older Laser Marking Methods
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,www.lasermarkingcnc.com 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,
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,www.lasermarkingcnc.com 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.

Lasers Offer Cheap Industrial Processing, Surgical Possibilities
EU-funded scientists have developed efficient new fiber optic lasers that deliver short wavelengths for accurate
polymer material processing, at incredible strength and low cost. The consortium behind the new innovations,
developed through the ISLA project, is now in the process of marketing some of these cutting edge devices.
Polymers — which are lightweight yet strong — are used in numerous industries ranging from aerospace to chemicals.
Industrial lasers are used to slice and shape polymer materials for use in everything from laptops to solar panels.
Global competition has placed increasing pressure on profit margins, www.lasermarkingcnc.com pushing manufacturers to constantly innovate in
areas of product performance and production efficiency.
It is this industrial need that ISLA sought to address. The new fiber lasers developed by ISLA are just as powerful
as devices currently on the market, and most importantly offer cost-competitive production. While welding, cutting
and marking of plastics without the need for absorption-enhancing additives present the most obvious commercial
opportunities for these fiber lasers, the success of ISLA should also open up potential new applications in other
industrial sectors, such as surgery and optical coherence tomography (OCT) imaging.
In surgery, light can be delivered through a flexible fiber and be easily integrated into devices such as endoscopes
and microscopes. The targeted nature of the laser beam is also attractive to many surgeons, enabling them to access
tricky areas of the body and deliver targeted cutting while minimizing damage to surrounding tissue. The treatment of
varicose veins and tumor resection are two possible uses.
OCT imaging systems on the other hand are used in diverse range of sectors including art conservation and diagnostic
medicine. The imaging technique is used to uncover more detail in layers beneath oil paintings than is possible with
shorter-wavelength sources.
Recently the technology has also begun to be used in interventional cardiology to help diagnose coronary artery
disease. www.lasermarkingcnc.com While commercial fiber lasers are already available on the market, the ground-breaking components delivered
by ISLA mean that lasers may soon by far more cost competitive.
The ISLA consortium also successfully developed a new graphene-based mode-locker. Mode-locking is a technique in
optics by which a laser can be made to produce pulses of light of extremely short duration. Potential applications of
this laser technique include optical data storage and eye surgery.
Although the project was www.lasermarkingcnc.com officially completed in June 2015, characterization work is ongoing. Once this is finished,
the laser will be transferred for industrial testing at an applications laboratory in Hamburg, Germany. ISLA
consortium members will also take part in a dedicated session at the LASE conference, part of SPIE’s Photonics West
event in San Francisco in February 2016.

Diamonds are forever - 3D lasers will tag the precious stones
Scientists at the Lebedev Physical Institute in Moscow have modified a laser technology used in eye surgery in order
to mark diamonds. It makes 3D marking possible, but causes no damage to the precious stones.
Sergey Kudryashov graduated from Moscow State University. He had an internship at the Institute for Laser and Plasma
Physics at the University of Essen in Germany, studying the interaction of ultra-short laser pulses with matter.
Between 2001 and 2006, he worked at the University of Florida and at the University of Arkansas in the USA. He has
co-authored nearly 150 research papers and five patents in the USA and Russia.http://www.lasermarkingcnc.com Now he is senior research associate at
the Lebedev Physical Institute’s eye laser laboratory.
Diamond marking helps detect illegal cutting and makes it easier to find stolen jewelry and gems. At the same time,
it is essential that markings do not affect a gem’s aesthetic value. Our laboratory has developed and patented
micro-marking methods that do not damage the diamond and are invisible to the naked eye. We create a marking in a
matter of seconds by using femtosecond lasers, subjecting diamonds to brief but very powerful laser bursts.
Laser for eye surgery
Scientists have for a long time been studying the impact that femtosecond lasers have on glass, as well as living
cells. Together with experts from the Central Clinical Hospital of the Russian Academy of Sciences, we conducted
research in femtosecond laser eye surgery and then carried out similar experiments with diamonds at the Smolensk
Diamond Factory, 400 km to the west of Moscow.
As a result, we patented two methods of femtosecond laser diamond micro-marking. They differ by laser impact,
primarily its peak power. In the first one,http://www.lasermarkingcnc.com a diamond is subjected to femtosecond laser radiation to create a higher
concentration of point defects, vacancies (empty nods in the crystal lattice of a diamond), and interstitials (extra
carbon atoms located in interstitial space). In the second, microscopic speckles of graphite inclusions are created
inside a diamond by pin-pointing a weakening in the crystal lattice.
Scientists at the Lawrence Livermore National Laboratory in the USA created a similar technology, but instead of
lasers they used beams of low-energy electrons. Laser technology makes possible markings that are truly three-
dimensional because the ray can easily be focused at different depths inside a diamond.
How it works
Under the first method, vacancies can be tied by nitrogen atoms that are present in diamonds in varying concentration
and that form a nitrogen-vacancy center, a defect very useful for diamond marking. When exposed to visible light of a
certain spectrum, NV-centers become fluorescent. After this form of micro-marking the diamond remains completely
transparent. This marking can be seen only when the crystal is hit by a powerful laser in the green spectral region,
and the marking starts to give off red light.
The use of a femtosecond laser makes it possible to http://www.lasermarkingcnc.com achieve a localized effect inside a diamond. The use of small
aggregations of NV-centers leave a “picture” (a drawing, a bar code, a text) that will not damage the quality of
the gem or its value. As a result, microscopic defects are present only inside a diamond; there are none on the
surface. These defects are not more than several microns in size, which is why they are invisible to the naked eye.
Under the second method, only with special lighting can the microscopic speckles of the graphite inclusions be seen.
This type of laser marking cannot be removed without breaking up the crystal. For example, we made a test and
engraved the Smolensk Diamond Factory's logo inside a diamond.
