单频光纤拉曼放大器的实验研究
Experimental research on single-frequency fiber Raman amplifier
摘要
Abstract
Single-frequency fiber Raman amplifier（SF-FRA） is known for the ability of all-band amplification,and it is very attractive for the amplification of single-frequency seed light at a special wavelength,such as 1178nm and 1271nm.The 1080nm single-frequency signal light is amplified by a 1031nm pump source,and the influences of seed power of single-frequency signal light,length of Raman gain fiber,pump scheme are experimentally investigated.The results show that the efficiency of SF-FRA increases with the enhancement of the single-frequency signal power and the length of Raman gain fiber.The efficiency of co-pump SF-FRA is higher than that of the counter-pump SF-FRA.The measure ments show that the linewidth of single-frequency signal light is not broadened obviously in the process of Raman amplification.The visibilities of the rapid-exposure pattern of far-field interference of single-frequency seed light and the amplified light are 0.814 and 0.719,respectively.The results show that the coherence of single-frequency signal light is affected by the SF-FRA more or less.These experimental results can provide a reference for designing other special wavelength SF-FRA.关键词
