Abstract
Laser excitation is generally initiated by 'dumping' energy from a stored supply into a flashlamp. The flashlamp produces light which is a mixture of both black-body type radiation and atomic line spectra. That portion of the flashlamp output energy spectrum which overlaps the pump bands of Nd.sup.3.sup.+ causes the inversion population necessary for laser action. It has been determined that the sequence in which energy is initially supplied to the flashlamp is an important parameter. More particularly, light output in the pump bands, and hence laser efficiency, is increased by slightly turning on the flashlamp at a predetermined interval of time prior to the main energy dump. Theory indicates that this method of triggering results in a larger ionic path diameter at the time of main energy release to the flashlamp.
