Structure and Advantages of Co2 laser tube
CO2 laser tube is a gas laser with CO2 gas as the working material.
The discharge tube is usually made of glass or quartz, filled with CO2 gas and other auxiliary gases (mainly helium and nitrogen, and usually a small amount of hydrogen or xenon); the electrode is usually made of nickel hollow cylinder; one end of the resonant cavity is a gilded total mirror, the other end is a partial mirror made of germanium or gallium arsenide.
