Gas molecular laser with good stability

Carbon dioxide laser is a gas molecular laser. The working substance is CO2 gas. The auxiliary gases are nitrogen, helium, xenon and hydrogen. Since the energy conversion efficiency of this laser is as high as 25%, it is often used as a high-power output laser. The wavelength of carbon dioxide laser is 10.6 microns, which is an invisible infrared light. It has good stability and is widely used.

Working principle and characteristics

The discharge tube of the CO2 laser is filled with a mixed gas of CO2, N2, He, etc., and its ratio and total pressure can vary within a certain range (generally: CO2: N2: He = 1: 0.5: 2.5 total pressure is 1066.58pa). Any molecule has three different forms of movement. One is the movement of electrons in the molecule, which determines the energy state of the electrons. The second is the vibration of atoms in the molecule, that is, the atoms keep vibrating periodically around their equilibrium position. This movement determines the vibration energy state of the molecule. The third is the rotation of the molecule, which determines the rotation energy state of the molecule. The CO2 laser uses the transition between the vibration and rotation energy levels of the CO2 molecule to generate lasers.
