摘　　要：研究了在宽带条件下非聚焦的同轴拉曼放大 ,采用CH4 作为放大拉曼介质 ,抽运源为 2 48nm的高功率KrF准分子激光系统 ,最高抽运能量为 1 5J。给出了拉曼链一级放大器的级增益随小信号增益系数及放大器气压的变化。最后讨论了限制同轴宽带抽运拉曼放大的因素。The characteristic of Raman amplifier with coaxal broadband laser pumping has been studied. CH 4 is chosen to be the active medium. The different gains of amplifier at different gas pressure and small signal gain are given. At last, the limitation of Raman amplification pumped by broadband laser beam is discussed.
