摘要

报道了LD端面抽运c切Nd:YVO4自拉曼倍频黄光激光器的研究. 采用10 mm长,二类临界相位匹配角 (θ=69°,ø=0°)切割的KTP晶体作为倍频晶体. 考虑到c切Nd:YVO4跃迁截面较小,所以通过对谐振腔及晶体膜系的严格设计,减少腔内插入损耗和衍射损耗. 最终在脉冲重复率为10 kHz,抽运功率为11.2 W下,获得了最高570 mW的倍频黄光激光输出,对应抽运光到倍频黄光的转化效率约为

Abstract

In this paper we report a LD end-pumped c-cut Nd:YVO4 yellow laser generated by sef-Raman conversion and frequency doubling. A 10-mm-length KTP with critical phase matching (θ=69°, ø=0°) cut is adopted as a second-harmonic generation. For the lower stimulated-emission cross section of c-cut Nd:YVO4 crystal, the resonator cavity and the coating of crystals are carefully designed to reduce the insert loss and diffraction loss. Finally, at a repetition rate of 10 kHz and an incident pump power of 11.2 W, the average power of yellow light up to 570 mW is achieved, corresponding to an overall diode-yellow conversion efficiency of 5.1% and a slope efficiency of 6.6%. The central wavelength is at 589.17 nm with a width of 0.2 nm, which is well fitted to the sodium D2 resonance radiation.
