摘要
报道了一台实现了双纵模窄线宽激光输出的光纤拉曼放大器。利用中心波长1 079.7 nm的双纵模窄线宽种子激光器获得了频率间隔1.4 GHz、功率比约3∶1的双纵模输出,各纵模的线宽约为10 MHz;再利用1 031 nm泵浦光对双纵模种子光进行拉曼放大,实现了1.07 W双纵模激光输出。拉曼放大过程中,两个纵模的线宽、频率间隔及功率比保持得很好。
A fiber Raman amplifier（FRA） with dual-longitudinal-modes narrow-linewidth output is reported.Firstly,the dual-longitudinal-modes seed light with 1.4 GHz frequency spacing and a power proportion of 3∶1 is obtained by a home-made dual-longitudinal-modes narrow-linewidth fiber laser operating at 1 079.7 nm.The linewidth of each longitudinal mode is about 10 MHz.Then,the dual-longitudinal-modes seed light is amplified to a maximal power of 1.07 W with 1 031 nm pump source.The linewidth,frequency spacing and power proportion of the two longitudinal modes of the seed light have been maintained during the amplification.
