摘要
实验研究了基于多周期的掺镁铌酸锂晶体光参量振荡器(OPO),分析了光学参量振荡器的输出光谱特性。实验中,采用激光二极管(LD)端面抽运的声光调Q Nd:YVO4激光器作为光参量振荡器的抽运源,谐振腔采用双凹腔结构。在调Q开关重复频率为10 kHz,周期极化掺镁铌酸锂(PPMgLN)晶体的温度为25.4 ℃的条件下,实验测得光学参量振荡器的振荡阈值为110 mW。当输入的抽运光的平均功率为325 mW时,获得了平均功率为84 mW的信号光输出,其光-光转换效率为25.8%。通过改变周期极化掺镁铌酸锂晶体的温度(25.4~120 ℃)和极化周期(28.5~30.5 μm),实现了信号光在1449.6~1635 nm范围内的可调谐输出。在室温25.4 ℃时,观测到了抽运光与信号光的和频光的光谱。实验结果表明,光参量振荡器输出光谱的半峰全宽(FWHM)小于0.5 nm。
Abstract
Temperature tuning and domain period tuning optical parametric oscillator based on periodically poled MgO doped lithium niobate (PPMgLN) in singly-resonant was studied experimentally. The output spectrum of optical parametric oscillator was discussed. A laser diode (LD) end-pumped acousto-optically Q-switched Nd:YVO4 laser was used as the pump source. The double-concave cavity structure was employed as PPMgLN-optical parametric oscillator (OPO) resonance cavity. Under Q-switch repetition rate of 10 kHz and temperature of 25.4 ℃, the threshold pump power of 110 mW is gained. The signal output power of 84 mW is obtained with a pump power of 325 mW and optical-optical conversion efficiency is 25.8%. It generates signal wave-lengths tunable in the range of 1449.6~1635 nm by temperature tuning and domain period tuning of PPMgLN. The spectrum from frequency mixing between the pump and signal is obtained at 25.4 ℃. The experimental results show that the full-width at half-maximum (FWHM) of output spectrum is less than 0.5 nm.
