  • 摘要:

    为改善高功率掺铥光纤激光器(TDFL)的输出性能,提高系统的光-光转化效率,研制了一种全光纤主振荡功率放大结构(MOPA)的高功率TDFL,可在连续(CW)和准连续(QCW)两种模式下工作。首先,搭建了激光振荡器,对种子源激光器的输出特性进行研究。接着,搭建掺铥光纤放大器,并将其与激光振荡器连接,研究MOPA结构光纤激光器的输出特性。最后,在QCW调制模式下,分析MOPA结构光纤激光器的脉冲特性。结果表明:激光振荡器实现了中心波长为1940 nm连续稳定的激光输出,最高平均输出功率为18.56 W,斜率效率为54.84%,且光谱无拉曼成分。利用该低功率连续激光作为种子源经过自制的掺铥光纤放大器后,平均输出功率可达66.9 W,斜率效率为48.48%。当系统在QCW模式下工作时,可以实现对频率和占空比的调节,且当频率为75 Hz,占空比为10%时,经计算其峰值功率为80.3 W。该研究方案对研制2 μm波段更高功率的MOPA激光器具有参考意义。
