Abstract

In this study, a YAG frequency-doubled pulsed laser with no Q-switch was constructed for the optical measurements under high-velocity phenomena. The laser consisted of the doubled-elliptical pump cavity with a Nd:YAG rod and two xenon flash lamps, the optical resonator with a KTP crystal, and the high-voltage pulsed electrical source. The stimulated emission of the frequency-doubled pulsed laser of 532 nm in wavelength was confirmed by a spectrometer. The laser output power was estimated to be larger than 4 kW by a pyroelectric joulemeter. The delay time from trigger signal and the effective time duration were about 40 and 65 microsecond(s) , respectively.
