Discharge Current Modulation to Obtain the Pulse Operation of a Power CO2 Laser, with Continuous Flow of the Gas

In the first part of the article there´re presented pulse excitation methods of CO₂ lasers, which permit the growth of the number of their applications in material processing. In the second part of the article it is presented a pulse excitation system of CO₂ lasers, with continuous flow of the gas, with electrical discharge in glass pipes, which allows the pulse operation of the laser and automatic control of its parameters during the material processing. By Spice simulation was tested in time and frequency domains the Half-Bridge converter, and it was analyzed its stability.
