Industrial Laser Marking
Industrial laser marking system is a process of marking an object directly by changing the surface properties of the material through the use of a laser to achieve a visible contrast.
L - light
A - amplification by
S - stimulated
E - emission of
R - radiation
Laser is amplified light coherent and monochromatic
Ordinary light, like sunlight, is made up of many different wavelengths, or colors, of light.
SUNLIGHT (many different colors)
First, the light from a laser contains exactly one color or wavelength rather than a lot of different wavelengths. Scientists say that laser light is "monochromatic," meaning of one color.
LED: one color (monochromatic) and waves not in phase (non-coherent)
Second, all the wavelengths are in phase.. All the wave crests (high points) and troughs (low points) are lined up. Scientists say the laser light is "coherent."
LASER: One color (monochromatic) and waves are in phase (coherent)
Different types of lasers (Fiber, CO2, DPSS)
To cover the maximum number of substrates, we have use different types of laser. Each laser generates a specific wavelength that will be absorbed by the material.
Important! Laser is amplified light with a specific WL. Good absorption = good marking result.

Benefits of Laser Marking
Industrial laser marking is ideal for both identification, to ensure legal compliance and industry standards are met, as well as decorative purposes, to deliver added value and protect your brand.
Other key benefits of laser marking:
-
Permanent marking – lifelong mark, good for anti-counterfeiting
-
High precision marking – micro-codes, hi-res graphics
-
High flexibility – Mark is created in software
-
High versatility – Can be used on many different materials
-
Non-contact – No tooling required, little risk of component damage due to clamping
-
No consumables – The latest fiber, DPSS and CO2 lasers have no consumable parts and extremely long life-times
-
Environmental responsibility – Clean technology, no harmful emissions, energy efficiency
Comparison of laser marking vs. other technologies
Laser marking often has lowest cost of ownership and is the most environmentally friendly marking technology. Overcome objections to high initial investment by focusing on operating cost and total cost of ownership.
