Introduce concept about the carbon dioxide laser.

A test target is vaporized and bursts within flame onto irradiation through a high power continuous wave carbon dioxide laser emitting tens of kilowatts of infrared light. The CO2 laser (carbon dioxide laser) was one of the earliest gas lasers to be developed, and is even one of the most helpful.

Carbon dioxide lasers are the highest-power regulates wave lasers which are currently obtainable. They are also rather efficient: the ratio of output power to pump power can be as huge as 20 percent.

The carbon dioxide laser produces a beam of infrared light along with the principal wavelength bands centering approx 9.4 and 10.6 micrometers.
