4 Types of Laser Engraving Machines
Laser machines today have become an integral part
of the everyday life of fabricators.
Understanding its basics, difference, and use is
essential. Let's discuss types of laser machines
and its importance.

• Fiber Laser
• Fiber laser marking technology is growing in
  recent times. It is one of the most useful
  marking technologies in the laser engraving
  market. Its power level ranges from 20 to 50
  watts.
• They are a perfect solution for depth etching or
  engraving. Additionally, they provide perfect
  results even on hard metals or high power
  systems with small spots.
• High beam quality and small spot size with large
  lenses, allows fiber lasers for small batch
  marking applications. Make sure to use the
  correct laser parts like Amada parts or fanuc
  parts online as they play vital roles.
• Applications
• Color marking
• It creates various shades of colors on a material
  with speed, power, frequency, and pulse width.
  The best result on color marking happens on
  stainless steel and aluminum.

• Another form of color marking is removing color.
  Here, you can mark and remove color on coated
  materials to reveal an underlying material of a
  different color. This technology is useful for
  fittings, labels, and packaging materials.
• Annealing
• It hardens the metal surfaces using a laser which
  enables production of various types of colors
  known as color laser marking. In this process we
  can achieve different colors like green, red,
  and yellow.
• Foaming
• Here, the targeted area on the material is
  lighter than the rest of the part of the
  material.
• Carbonizing
• Carbonizing destroys the carbon bonds which are
  useful to create shades of dark marked areas. It
  happens without affecting the surface of
  material. It is useful for light plastics and
  organic materials.

• Night and day marking
• Fiber laser technology is useful to deliver marks
  that are easy to see in day time and illuminate
  by night. This can be useful for dashboards,
  reflectors, number plates, watches health and
  safety, and door signs.
• 2. Green Laser
• Green laser marking machines designing is useful
  to mark reflective materials. They work on very
  sensitive substances like silicon wafers. It
  exhibits good work with ease and high precision.
  It operates in the green near IR visible light
  spectrum and power range of 5-10 watts.
• They are best suitable for soft plastics, PCB
  boards, integrated circuit chips and for marking
  of solar cells of various materials.
• The advantages of 532 nm wavelength includes
  great intake across many types of materials. It
  uses mitigated thermal energy which allows it to
  mark substances which have high wavelength.
  Green laser markers also provide very tight spot
  sizes of 10 µm.

3. UV Laser Ultraviolet represents a band of
electromagnetic spectrum with wavelengths from
10 nm to 400 nm. They are shorter than those of
visible light but longer than x-rays. Long
wavelength UV is bad at ionizing radiation,
because photons do not have the energy to ionize
atoms. But, they can cause chemical reactions
that make substances glow or fluoresce. As a
result, the chemical and biological effects of UV
are wider than simple heating. Most applications
of UV radiation happen because of its
interactions with organic molecules. Gas lasers,
solid state lasers, and diodes are useful to make
machines which emit ultraviolet rays. The lasers
are available which cover the entire UV range.
Since the discovery of the laser machine, it is
possible to avail intense ultraviolet
light. Researchers explored the unique
properties of this new light and optimized
practical applications.

4. CO2 Laser CO2 laser marking machines usually
have sealed tube laser marking systems. They are
galvo-steered beams for marking nonmetal
surfaces like wood glass, quartz, and
ceramics. They can also mark fabrics and other
organic materials, operating at wavelengths of
10,600nm. These machines are useful to produce
barcodes, serial numbers, and logos on metals
and other surfaces. When laser marking bare
metal uses CO2 laser, it uses a special marking
agent and is useful to treat the metal before
engraving. Once the laser beam applies the heat
from laser bonds the marking agent to the metal,
resulting in a high contrast permanent
mark. These machines are fast, affordable,
oldest types of engravers, markers. They even
mark organic materials like wood, ceramics, and
many more. Additionally, you can use CO2 laser
machines for Windows and Linux.
