High-power copper bromide vapor laser

Abstract A large-volume single-tube CuBr vapor laser, oscillating on the atomic copper self-terminating lines of λ 510.6 nm and λ 578.2 nm, is described. Characteristics of the nanosecond pulsed longitudinal discharge excitation for a maximum output power on these laser lines are found. A record-high average laser power of 140 W for atomic self-terminating CuBr vapor lasers is reported.
