The results of experimental studies on the lasing characteristics of a copper vapor laser on self-terminating transitions (active medium: CuBr+Ne+H2) pumped by pulses with subnanosecond rise times are presented. In a burst mode, a stable average output power per unit length of 65 W/m was achieved in a gas discharge tube with a diameter of 1.1 cm at a pulse repetition frequency of up to 100 kHz, with a lasing efficiency of 0.6 % relative to the energy stored in the operating capacitor. Keywords: copper vapor laser, pulses, subnanosecond rise time.
