单模光纤中受激喇曼散射光放大

LIGHT AMPLIFICATION OF THE STIMULATED RAMAN SCATTERING IN SINGLE-MODE FIBER

本文报道在单模光纤中,背向受激喇曼散射(BSRS)光放大的研究。所用的泵浦源为声光Q开关Nd^(+3):YAG激光器,工作波长1.064μm。信号源为多模光纤在1.064μm Q开关Nd^(+3):YAG激光泵浦下产生的第一级Stokes线,波长为1.117μm.在1.117μm处,获得了17.6dB的Raman增益。

The investigation of the light amplification by backward stimulated Raman scattering in single mode fiber is described in this paper. 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.
