【摘要】：基于掺氧化镁的周期性极化铌酸锂(MgO:PPLN)晶体,研究了连续波种子光注入结构的光参量放大器(OPA)。采用重复频率为10kHz、最大平均输出功率为6 W的1064nm高频脉冲激光作为抽运源,晶体的极化周期为31.02μm,在119℃工作温度下,将连续分布式反馈激光器(DFB)作为种子注入,在1652.3nm处得到最大平均功率为125mW的OPA信号光输出,量子转换效率为7.47%。实验通过改变注入种子光波长,实现了信号光nm级范围的调谐输出。信号光通过10m外甲烷气池,观察到其光谱强度明显下降,初步验证了信号光在甲烷遥测领域的可行性。与用种子光直接检测相比,信号光强度更高,检测距离及灵敏度均有较大优势。

A 1064nm high frequency pulse laser with a repetition rate of 10 kHz and a maximum average output power of 6 W was used as the pumping source. The polarization period of the crystal was 31.02 渭 m. The continuous distributed feedback laser (DFB) was injected as the seed at 119 鈩，
