Question

3. Explain the fundamental parts of the Co2 laser in details.

Answer 1

CO2 laser was one of the earliest gas lasers to be developed, and is still one of the most useful. CO2 lasers are the highest-power continuous wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%.The CO2 laser produces a beam of infrared light with the principal wavelength bands centering around 9.4 and 10.6 micrometers.

Fundamental componets of CO2 laser

1. CO2 Laser Beam Expander

The laser beam expander has two purpose: expand the diameter of the laser beam, and reduce the divergence angle of the laser beam.CO2 laser beam expander are widely used in laser marking, engraving, drilling machines. The Single-chip Flat-field Scanning Mirror has optimized the wide-angle and long focal-length light path, it is widely applied in wide scan range situation.

2 .CO2 Laser Tube

It is used for Laser Cutting Engraving

3.Copper CU Reflection Mirror

This optical element is used for planar reflecting the laser beam. It is an important component of the laser system.

The biggest advantage of Copper mirror is it has high damage threshold. So it can be used in some high power laser systems such as laser engraving machines and laser cutting machines.
As a kind of high quality Copper mirrors, it has high reflectance and low flatness. Using the high quality surface coating will protect the layer of Copper not to damage, and increases the Copper layer reflection efficiency.It has countless applications, such as Astronomy, Industry, Medicine, Optical Communication, etc.

4. Chiller for Cooling CO2 Laser Tube

5. Power supply for energy
