Influence of the excitation circuits on the CuBr laser performance

A comparative study has been carried out of the output characteristics, electric parameters, and main kinetic plasma processes concerning CuBr laser performance during the excitation pulse. Four electric circuits were used for CuBr vapor laser excitation: WPC (without peaking capacitor); OC (ordinary circuit, i.e., with a peaking capacitor); IPC (interacting peaking circuits), and IC (interacting circuits). The calculated and experimental values are in very good agreement. The improvement of the CuBr laser performance from WPC- to IC-excitation (the laser power and efficiency increase three times) is mainly attributed to the increased physical laser efficiency, which concerns the electrooptic energy conversion with regard to plasma kinetic processes.<
