Silver Co2 Laser Source

CO2 laser is a kind of molecular laser, the main substance is carbon dioxide molecule.Like other gas lasers, CO2 lasers work in complex excited emission process.Molecules have three different kinds of motion, namely, the motion of electrons in molecules, which determines the electronic energy state of molecules;The second is the vibrational state of atoms in molecules, where atoms periodically vibrate around their equilibrium positions -- and depend on their vibrational energy states.The third is the rotation of molecules, that is, molecules rotate continuously in space as a whole. This motion determines the rotational energy state of molecules.The molecular motion is extremely complicated, so are the energy levels.
CO2 laser, the main work of material by CO nitrogen, helium of three kinds of gas.

The CO - produce laser radiation gas, nitrogen and helium as auxiliary gases.The added helium can accelerate the thermal relaxation process of the 010 energy level, so it is advantageous to pump out the laser energy levels of 100 and 020.Nitrogen to join mainly in CO - laser energy transfer role, for the CO - high-power laser level the number of particles on the accumulation and high efficient laser output play a strong role.CO - molecular laser transition energy level diagram of CO - laser excitation conditions: discharge tube, usually enter dozens of hundreds of mA mA or dc current.During discharge, nitrogen molecules in the mixture in the discharge tube are excited by the impact of electrons.Then inspired to nitrogen molecules, they collide and CO - molecules, N2 convey their energy to CO2 molecules, CO - molecules from low energy level transition to high level population inversion is formed on a laser.
