论文摘要
我们演示了基于分级索引多模纤维的全纤维时空模式锁定激光器。由于分级索引多模纤维设备的高损伤阈值，输出单脉冲能量达到11.67 NJ。由于自我清洁效果，与连续波状态相比，模式锁定状态下的光束质量得到了显着提高。通过放大多模纤维放大器中的脉冲，可以基于分级索引MMF在全纤维系统中获得具有远光质量的高功率脉冲。
We demonstrate an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber. Due to the high damage threshold of graded-index multimode fiber devices, the output single-pulse energy reach up to 11.67 nJ. The beam quality at mode-locked state is significantly improved compared with continuous wave state as a result of the self-cleaning effect. By amplifying the pulse in the multimode fiber amplifier, high power pulses with high beam quality can be obtained in the all-fiber system based on graded-index MMFs.
