Abstract
Pulse-periodic CO2 lasers with high average power output are required for many applications, for example, high precision cutting, welding, drilling, and isotope separation, initiation of chemical reactions, and so on. Generally, the main excitation sources for this kind of laser are modulated rf or SD (silent discharge) power supplies, and hydrogen thyratron pulsers with strong pulse output. But the above power supplies are too complicated and expensive in comparison with the DC power supply.
