利用半导体激光器抽运的色散位移单模光纤作为分布式光纤拉曼放大器，对增益开关分布反馈半导体激光器产生的变换限幅（TL）脉冲进行了线性压缩和光谱窗口处理。在总增益为2.4 dB的分布式光纤拉曼放大器中，即使不使用孤子作为初始光脉冲，也能成功地将初始TL光脉冲渐近压缩为3.6 ps的几乎纯孤子。实验结果得到了光束传播法数值计算的支持。
Using a dispersion-shifted single-mode fiber pumped by laser diodes as a distributed fiber Raman amplifier, the authors adiabatically compressed transform-limited (TL) pulses generated by a gain-switched distributed-feedback laser diode followed by linear compression and a spectral window. The initial TL pulses were successfully compressed asymptotically to almost pure solitons as short as 3.6 ps at the 2.4 dB total gain of a distributed fiber Raman amplifier, even without using solitons as the initial pulses. The experimental results are well supported by numerical calculations made with the beam propagation method.>
