Investigation of operational parameters on copper bromide laser output power

Physics, Laser

Keywords: Copper Bromide Laser, Operational parameter, He and Ne buffer gas

Abstract

In this work, a copper bromide laser with an active medium length of 58 cm and an inner diameter of 20 mm was designed and constructed. He and Ne were used as buffer gases. The effect of reservoir temperature, He and Ne buffer gas pressure, frequency and electrical input power on the output power were investigated. The result of experiments shows that an optimum laser efficiency was obtained at the electrical input power of 2.1kW and corresponding operational temperature of 510 oC. The maximum output powers, 4 and 6 W, with use of He and Ne buffer gases, were determined at pressures 11 and 24 torr, respectively.
