摘要
对氢气中的超宽带拉曼脉冲压缩进行了实验研究，利用工作在阈值附近的拉曼振荡器，当准分子激光抽运源的脉冲宽度为２３ ｎｓ时，得到了６ ｎｓ的拉曼种子光，并采用反向拉曼放大得到了放大倍数近３ 倍的放大拉曼光。并就实验中的气压和气体掺杂对实验结果的影响进行了讨论。
Experiments of superbroadband Raman compression in hydrogen gases were conducted. The Raman seeds of 6 ns pulse duration were obtained from a near threshold oscillator pumped by an excimer laser pulse of 23 ns. Then the seeds were amplified 3 times in a backward Raman amplifier. The effects of pressure and mixture of Raman gases were discussed.
