Analysis of small-bore copper-vapor laser by physical simulation

Abstract

The copper–vapor laser physical simulation code applied to different diameter small-bore copper–vapor laser (CVL) is described. The kinetic equations, coefficients, and initial parameters of population density are presented. The discharge and lasing characteristics of the copper–vapor laser under a series of operation conditions are discussed. Good agreement exists between the theoretical and experimental results. As a calculation result, the population densities of the laser upper and lower level under different charging voltage for a 4 cm diameter laser operation condition are presented. An avalanche of the upper laser level population density appears as the exciting voltage increases, so the optimized charging voltage when the laser outpower is maximum can be explained exactly. ©1999 John Wiley & Sons, Inc.
