Abstract
It is shown that the use of a power supply with a pulsed step charge of the working capacitance for a CuBr laser excitation allows lasing in the single pulse mode with repetition frequencies from 330 Hz. The effective energy input into the laser medium with operating capacitances from 6.8 to 20.4 nF occurs in 5-11 charge stages. An increase in the pulse lasing energy to 3 mJ is facilitated by increases in the working capacitance and charge voltage.
