Abstract

We report 95% conversion from the optimized Q-switched fundamental output to green output in the self-frequency doubling material Yb:YAB. Maximum average green powers of 2.27 W were obtained at 520-522 nm. The diode-to-green conversion efficiency was 26%. Operating at 10 kHz we obtained pulse widths ranging from 100 ns to 2 μs. The pulse duration was critically dependent on the strength of the nonlinear coupling and on the time that the acousto-optic Q switch was open. Numerical modeling of the system is found to predict the observed pulse-lengthening effect as well as high-average-power second-harmonic generation over a broad wavelength range.
