【Abstract】 In the paper, optical fiber-nitrogen Stimulated Raman Scatting (SRS) gain medium is produced by diffused nitrogen at high-Temperature and high-pressure. Experimental set up for measured SRS spectrum and transmission mode photograph are given. The relation of threshold power and spectrum width with pumping light power are discussed, Experimental results is accord with theoretic date. At one time, feebleness coupled mode of nitrogen molecular with silica molecule is observed.更多还原
