Scaling of the discharge heated copper vapor laser
Abstract
Optimum working temperature of 1650 ± 50°C was determined for the longitudinal copper vapor laser. Using neon in the pressure range 20-200 torr we were able to operate lasers of volumes up to 600 cm 3 at optimum temperature. Power output was proportional to tube volume and efficiency to the square of tube radius. Average power of 19.5 W was obtained at 4 kHz with 0.7% efficiency.
