The recovery of steady-state lasing in a CuBr laser operating in the train mode is studied with the use of a computer-based control system. The control system provided the repetitively-pulsed, train, and waiting modes. The dependences of the recovery time on the pause duration and the strorage capacitor are derived. The specific recover times are determined; their dependences on the pause duration in the train mode are analyzed. A time delay between the start of pump pulses and appearance of lasing pulses is shown. The time where lasing is absent increases in the pause duration range from 0.2 to 10 ms; this time is set to about 15 ms if a pause is equal or longer than 10 ms.
