Abstract

A small-bore (12.5 mm) hybrid laser delivers its highest average output power for a gas flow rate of around 1 liter/atm/hr^-1 and an HBr pressure of 2 - 4 torr in 34 torr Ne. It is estimated that the atomic bromine pressure at the wall is approximately mtorr. The number density of copper in atomic and molecular forms averaged throughout the tube is 4 multiplied by 10¹⁶ cm^-3. Significant numbers of Cu_xBr_x polymers and CuH must exist in the laser discharge to lock up the large pool of copper atoms in the discharge. The copper hybrid laser produced an average output power of 12.8 W, corresponding to a specific average output power of 348 mW/cm^-3, at a PRF of 35 kHz.
