摘　　要：ASC(绝热孤子压缩)是获取超短脉冲的重要手段之一。提出一种基于拉曼增益辅助色散渐减光纤环镜的ASC方案。利用长度为3.0km的线性DDF(色散渐减光纤)构成NOLM(非线性光纤环镜),并辅以7dB/km的分布拉曼增益,成功将10ps的光脉冲绝热压缩至195.3fs,压缩因子为51.2,基座能量为11.61%。研究结果表明,采用这种压缩方案既可以获得较高的压缩因子,还能有效抑制压缩脉冲的基座。Adiabatic Soliton Compression （ASC） is an important means for obtaining ultra-short pulses. In this paper, a novel ASC scheme based on Nonlinear Optical Loop Mirror （NOLM） is proposed, which is made up of a 3 km long linear Dispersion Decreasing Fiber （DDF） assisted by 7 dB/km distributed Raman gain. In this scheme, 10 ps pulses are compressed to 195.3 Is, with a compression factor of 51.2 and the pedestal energy of only 11.61%, which indicate that this scheme can not only in- crease the compression factor, but also effectively suppresses the pedestal, of compressed pulses.
