摘要

报道了880 nm激光二极管(LD)共振抽运的连续波(CW)NdYVO4-PPLN内腔单谐振光学参量振荡器(ICSRO)。在21.9 W抽运功率下,获得了1.54 W的3.66 μm CW中红外闲频光输出,光-光转换效率为7.0%;与808 nm传统抽运相比,共振抽运ICSRO在振荡阈值、输出功率、转换效率和功率稳定性等方面都显示出明显优势。针对高抽运功率下逆转换过程影响单谐振光学参量振荡器(SRO)转换效率的问题,研究了振荡信号光的耦合输出透射率对SRO阈值和下转换效率的影响。通过提高振荡光输出镜透射率优化SRO阈值,可在高抽运功率下保持下转换效率的同时获得高效的信号光输出;21.4 W抽运功率下同时获得1.54 W闲频光和5.03 W信号光输出,总提取效率为30.2%。

Abstract

A continuous-wave (CW) tunable NdYVO4-PPLN intra-cavity resonance single oscillator (ICSRO) under 880 nm laser diode (LD) resonance pumping is reported. 1.54 W maximum idler output power at 3.66 μm is obtained under the pump power of 21.9 W, corresponding to an optical-optical conversion efficiency of 7.0%. The ICSRO under 880 nm in-band pumping shows significant improvements in threshold, output power, conversion efficiency and power stability compared with that under 808 nm traditional pumping. Since the back-conversion process harms the single resonance oscillator (SRO) down-conversion efficiency under high pump power, the influence of output coupler transmittance on SRO threshold and down-conversion efficiency is investigated. By increasing the output coupling of resonant signal to raise the SRO threshold, the down-conversion efficiency can be maintained under high pump power and efficient signal output can be obtained. 1.54 W idler output and 5.03 W signal output are obtained under the pump power of 21.4 W, corresponding to a total extraction efficiency of 30.2%.
