Abstract
We report generation of 4.3mW coherent, diffraction-limited blue-green light at 491nm by single-pass frequency doubling of continuous-wave m aster oscillator power amplifier diode laser radiation in a 9.5mm long KNbO3 crystal. A normalized conversion efficiency of up to 1.2% W-1 c m(-1) was reached. The root-mean-square fluctuations of the second har monic output power was found to be as low as 0.1% and the long-term dr ift over 6 hours was +/- 1%.
