C02 Laser Everything You Need to Know
If we go back to laser cutters' history, we
would see C02 lasers on the top. And if you look
at the current trends, Co2 still is one of the
most useful. The technology that Kumar Patel
invented in 1964 is still one of the finest
laser cutting/engraving machines. And no doubt,
you can get Trumpf laser parts for the same.
Bystronic also provides Bystronic laser
consumables for the Co2 lasers. It provides
high power, precision, and consistency. The sole
reason why many businesses use Co2 lasers for
personalization. Their engravers and cutters are
so precise that they can create any design on
any material. It doesn't matter if it's wood,
metal, plastic, or paper. How does a Co2 Laser
Works? In Co2 laser cutters, the light is
produced when electricity runs through a
glass-filled tube. There are mirrors on both ends
of the tube. One is reflective, and the other
allows light to pass through it. These mirrors
help laser beams to cut. The gas in the

tube consists of helium, carbon dioxide,
hydrogen, and nitrogen. The nitrogen molecules
in the tube get charged. They start producing
high-energy vibrations that excite Co2 molecules.
And then comes a stage of population inversion
where nitrogen has to release the energy. It
then comes in contact with cold helium particles
and releases energy in the form of photons that
produce a beam of light. The released light is
more potent than normal light because of the
mirrors. So, the mirrors reflect the light and
cause waves to build in intensity. The light
passes through the partially reflective mirror
only when it's bright enough. Since it's
infrared, it has a high wavelength and can cut
any material. The intensity of the light
vaporizes the material, thereby leaving a smooth
touch. Depending on the material you want to
engrave or cut, you can decrease the power and
speed.

• Co2 Laser Specifications Lenses, Lifetime, and
  Spare Parts
• Lenses
• Just like the different power capacities of Co2,
  there are different types of lenses available
  for Co2. Based on their focal length, their
  purpose differs. Let's check them out.
• Lens 1.5"
• To engrave small letters or details, these lens
  resolutions are highly recommended. They produce
  a laser beam between 0.0762 and 0.1651mm. They
  are suitable for materials with a thickness of
  less than 1.8mm.
• Lens 2"
• These are the standard lenses available in most
  lasers. They produce a beam between 0.1 and
  0.18mm. They are best to cut or engrave
  materials with a thickness between 300 and 600
  dpi.

3. Lens 4" They produce a more focused cut at a
vertical distance. Experts highly recommend
these lenses for engraving and cutting thick
material. Lifetime The lifetime of your laser
lens highly depends on its use and handling.
Maintenance is another factor that defines its
lifetime. Keeping this aside, the quality of the
consumables and parts also affects its
durability. For some lenses, the approx
durability is around 6 to 9 months. So before
you buy one, discuss it with your
provider. Spare Parts Lasers of any type highly
depend on their consumables and parts. So when
you replace the parts, make sure they are of top
brands. We would recommend going with Trumpf
laser parts. For consumables, Bystronic laser
consumables.

Also, check out other brands such as Hypertherm,
Fanuc, Mazak, etc. Uses of Co2 Lasers We
already saw that they are the best option for
personalization and high precision cutting.
Besides this, you can also use them for welding
or in the additive manufacturing process of
selective laser sintering. Co2 lasers are also
useful in the medical field. Many surgical
procedures utilize Co2 lasers as water could
easily absorb the high frequency of light and
make tissues. Laser surgeries and skin
resurfacing also make use of Co2 lasers. They
are also used to treat skin conditions such as
hirsuties papillaris genitalis by removing
bumps. Other branches such as dentistry,
gynecology also use these lasers. Artists
providing custom wooden engraving designs use it
for personalization.
