The paper presents the results of the research and development of the CuBr laser with continuous control of each pulse energy. The prototype consists of a large volume CuBr active element with an unstable cavity, two high voltage pulses generators and control system. The HBr additive was used to increase the laser energy-frequency characteristics. Control of laser pulses energy has been provided by high-voltage preionization pulses. The linear control of output power from 5 W to 0 have been demonstrated. The metastable atom population is the major factor in the energy control. The dependence of the preionization pulse energy for full suppression on the active media operating mode (CuBr concentration, pumping energy etc.) was studied. The ratio between excitation pulse energy and preionization pulse energy for full suppression of the lasing changing from 18 to 25.
