Computer study of the gas temperature profile in copper and copper vapor halide lasers

摘要

Due to their unique radiation properties, metal vapor lasers find a variety of applications, including being used as a high- brightness amplifier in new active optical systems. This type of systems has been actively developed in recent years and is applied for visual control of fast processes in screening the background illuminations. A computer model is built and applied to an existing laser source allowing to determine the radial distribution of gas temperature in the cross section of the laser tube. Computations are performed using a preset qualitative type radial distribution of the electric power supplied to the gas discharge. The influence of the electric power supplied to the gas discharge and the wall temperature on the thermal resistance of the gas discharge was evaluated by means of computer simulations. The proposed methodology allows the planning of experiments and developing new laser sources with improved output characteristics.
