Generation of high-power blue light in periodically-poled LiNbO3 (PPLN)
Generation of high-power blue light in periodically-poled LiNbO3 (PPLN)
We report the generation of 450mW average blue (473nm) power by frequency-doubling of a diode-pumped 946nm Nd:YAG laser. Pulsed operation at high repetition rate (~160 kHz) was achieved by driving the relaxation oscillations of the laser. A 40% conversion efficiency to the second harmonic is obtained in a single-pass, extra-cavity, first-order, quasi phase-matched process using periodically-poled lithium niobate (period 4.5µm, thickness 0.5mm and length 15mm) at 140°C. The resulting high-power, blue beam is circular in profile and near-diffraction-limited, indicating that photorefractive effects do not appear to limit device performance.

Abstract
We report the generation of 450mW average blue (473nm) power by frequency-doubling of a diode-pumped 946nm Nd:YAG laser. Pulsed operation at high repetition rate (~160 kHz) was achieved by driving the relaxation oscillations of the laser. A 40% conversion efficiency to the second harmonic is obtained in a single-pass, extra-cavity, first-order, quasi phase-matched process using periodically-poled lithium niobate (period 4.5µm, thickness 0.5mm and length 15mm) at 140°C. The resulting high-power, blue beam is circular in profile and near-diffraction-limited, indicating that photorefractive effects do not appear to limit device performance.
