ABSTRACT:
The initially high amplitude laser output pulses at the start of a string of pulses from a continuously pumped, repetitively, Q-switched Nd:YAG laser are reduced in amplitude by reducing the current to the krypton arc lamp pumping light source by about 5 amperes for a time of about one-half to about one millisecond prior to gating the Q-switch.
