Abstract
The dynamical behaviour of a Q-switched, flashlamp-pumped Nd: YAG lase r cooled to 253 K was investigated. The build-up time of photons in th e resonator at 946 nm was 20 times longer than for 1064 nm generation in a Q-mode of operation. A type I second- and fourth-harmonic generat ion was obtained in KDP and BBO nonlinear optical crystals. A reproduc ible spectral line width of the second-harmonic generation deltanu = 2 .6 GHz within a tuning range of DELTAnu = 146 GHz was achieved. A comp arison between experimental and theoretical results is presented.
