Low frequency lasing mode of CuBr laser operation (50 Hz) is made, using double-discharge excitation. Dissociating and main pumping pulses are applied to the active medium. The main feature of the utilized excitation circuit is application of thyristor-based pulser for dissociating pulse forming. Dependences of lasing energy on the dissociative and pumping pulse parameters are studied.
