CO2 Laser

The carbon dioxide laser (CO2 laser) is one of the earliest gas lasers to be developed and is still one of the most useful. Carbon dioxide lasers are the highest-power continuous wave lasers currently available. They can also operate in pulsed mode and are 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. The active laser medium (laser gain/amplification medium) is a gas discharge which is air cooled (water cooled in higher power applications).

High power CO2 lasers are frequently used in industrial applications for cutting and welding, while lower power CO2 lasers are used for engraving or marking. Their unique combination of versatility and low cost make CO2 lasers favorable for marking in a variety of settings in comparison with more expensive solid state laser alternatives.

CO2 lasers with output powers from 10 to 100W can be used successfully with a range of TherMark products. Most CO2 laser systems for engraving can operate in both rastering and vectoring mode. They are usually supplied with laser and automation control software that allows the user to have a full control over the laser operation and positioning.

Below is a list of laser manufacturers that produce CO2 lasers.
