利用拉曼孤子实现宽带拉曼脉冲压缩

Broadband Raman Pulse Compression in Raman Soliton Regimes

从拉曼散射方程出发 ,研究了利用拉曼孤子实现宽带拉曼脉冲压缩的机制 ,发现孤子脉冲的宽度随拉曼增益的增加而减小 ,并与抽运光的脉冲形状及相位结构有关。实验中利用 Xe Cl激光 /H2 系统初步实现了 50 %的压缩率 ,并将实验结果与理论进行了比较。

Based on the Raman equations, the dynamics of broadband Raman pulse compression in Raman soliton regimes were investigated. It is found that the duration of soliton decreased with the increase of the Raman gain and was related to the pump pulse profile and phase structure. A compression ratio up to 50% was observed in experiments with a XeCl laser/H 2 system. The experimental results were compared with the theoretical predictions.
