Paper Abstract

Copper vapor and copper halide lasers are the most efficient high-power lasers that operate directly in the visible spectral region. In order to scale these lasers to high average powers, it is important to determine the maximum output power that can be generated from a given volume of the active medium, and the discharge conditions for which it can be achieved. In this paper we describe the attainment of a record average specific output power for self-terminating atomic copper lasers of any type. We have performed our experiments with a narrow-bore (4.5 mm) copper bromide laser. From the active volume of 4.77 cm3 a maximum average output power of 6.7 W was reached, which corresponds to the record specific average power of 1.4 W/cm3. The discharge was excited with a pulse recurrence frequency of 52 kHz. The tube was sealed with pressure of 20 torr neon, to which was added 0.3 torr of hydrogen. We describe the design and construction of the laser tube, the excitation circuit and the discharge conditions which allowed these results to be obtained.
