本文从实验和数值两方面研究了双折射光纤中连续光束和超短孤子脉冲之间的正交偏振脉冲捕获现象。利用脉冲捕获和放大，我们演示了从连续波束产生的超短脉冲。产生的脉冲具有几乎变换受限的sech(2)形状和350fs的时间宽度。使用400 m长的低双折射光纤，获得的最大脉冲能量为300 pJ，相应的增益高达41 dB。
We investigated the phenomenon of orthogonally polarized pulse trapping between a continuous-wave beam and an ultrashort soliton pulse in birefringent fibers both experimentally and numerically. Using pulse trapping and amplification, we demonstrated ultrashort pulse generation from a continuous-wave beam. The generated pulse had a nearly transform-limited sech(2)-shape and a temporal width of 350 fs. The obtained maximum pulse energy was 300 pJ using a 400 m-long low-birefringence fiber, and the corresponding gain was as large as 41 dB.
