There is deduced analytical expression for maximum value of the volume discharge ignition frequency in dense gases. That expression indicates the way for achieve maximal values of pulse repetition rates in CO 2 -lasers at atmospheric and super-atmospheric pressures. The increasing of pulse repetition rates is connected with sectioning of main discharge gap and excitation of volume discharge in each section from separate pulse pumping generator. This work is devoted to describing of constructions and main characteristics of some types compact pulse generators with amplitude of voltage pulses up to 200 kV, rise-times about 10 nanoseconds and pulse energy per pulse up to 20 J. For reduction of rise-time of high-voltage pulses were used spark-discharge two electrodes commutators (sharpeners) at working pressures up to 100 atm.
