The pump light source is a acousto optic Q-switched Nd +3 : YAG laser operation at a wavelength of 1.064μm. The signal source is the first order stokes line at λ s =1.117μm generated by SRS in a muldi-mode pumped with a 1.064μm Qswitched Nd +3 : YAG laser. As a result of Raman gain of 17.6dB at a wavelength of 1.117μm is obtained. 光纤 喇曼散射 光放大 fiber Raman scattering light amplificakion 1992-01-01 2021-04-01 1
