| Abstract: | 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. |
