Abstract
Current supply means for a laser flash lamp contain a fast switch and control means which modulate the amplitude of each individual pulse with a presettable modulating frequency and depth of modulation. This permits higher peak envelope powers to be obtained at an unchanged mean power of the individual pulses so that the necessary threshold values can be better exceeded during materials processing. The amplitude modulation of the individual pulses also prevents undesirable shielding plasma from forming above the processing place.
