Power source for a laser flash lamp.

摘要

A power source for a laser flash lamp (2) contains a rapid switch (6) and a controller (10) which modulates the amplitude of each individual pulse at a predeterminable modulation frequency (Mf) and depth of modulation (MT). In this way, high peak powers can be achieved with unaltered mean power of the individual pulses, with the result that in the treatment of materials the necessary threshold values can be better exceeded. Also, by means of the amplitude modulation of the individual pulses, the formation of an undesired screening plasma above the treatment location is suppressed.
