A power supply for an IFP-800 flash lamp is described in which an 8000-/mu/F storage capacitor is partially discharged through a controlled thyristor switch. The storage capacitor is charged from eight charging circuits with intermediate storage devices. The pulses have repetition frequencies of 1-100 Hz and durations of 0.2-2 msec; the discharge current is 200-600 A. Tests of the supply have shown high reliability and the possibility of wide variation of the pulse parameters. The voltage on the storage capacitor is half that required with LC circuits to produce the same current; also, matching of the impedances of the lamp and circuit is unnecessary. The lamp is designed for optically pumping YAG process lasers.
