非临界相位匹配RTP晶体1.6μm光参量振荡器
Optical parametric oscillator at 1 .6μm based on non-critical phase matching RTP crystal
摘要
Abstract
This paper reports an intra-cavity rubidium titanyl phosphate(RTP)optical parametric oscillator producing the eye-safe light driven by LD end-pumping Nd:YAG laser.A non-critical phase matching RTP crystal with 4 mm×4 mm×20 mm in size was adopted for nonlinear optics crystal.The signal light output characteristics with different pulse repetition frequencies of Q-switcher were compared.With a diode pump power of 10.5 W and a pulse repetition frequency of 15 kHz,a maximum output power of 900 mW eye-safe laser at 1.62μm were achieved,with a diode to signal conversion efficiency up to 8.6%.The pulse widths for the 1.62μm signal light and 1.06μm fundamental light were about 4.6 and 8.2 ns,respectively.The center wave-length of signal light was about 1618 nm with a line-width less than 0.5 nm.关键词
