Abstract
Efficient second-harmonic generation from a pulsed parametric laser to 427 to 470 nm has been obtained in a KNbO3 crystal only 1.5 mm in length by angular tuning at room temperature. The energy conversion efficiency is over 40%. Single pulse blue light output reaches 60 kW in peak power. The angular dependence of a phase matching wavelength, the relation between conversion efficiency and fundamental intensity, and acceptable angular phase mismatch are studied and discussed.
