Study on threshold capabilities of a copper bromide vapor laser

Abstract

Abstract This paper presents theoretical and simulation results for the operating parameters of a copper bromide (CBr) laser. The CuBr active medium finds applications as both as a laser source and a vapor amplifier. A methodology is developed to serve as the basis for the solution of a two-dimensional quasi-stationary heat conductivity equation on the cross-section of the gas tube for modeling the temperature of the neutral gas and the electron temperature of the discharge. This methodology makes it possible to determine the maximum electrical power supplied and the maximum electron temperature in terms of thermal ionization and electric ionization resistance of the gas discharge. Analytical results are applied in computer simulations and for the assessment of parameters of an actual CuBr laser.
