The SNPs-based SAs showed large modulation depths and high maximum transmittances. With one of the SNPs-based SA, we built a passively -switched erbium-doped fiber laser (EDFL). Self-started -switching at 1564.5 nm in the EDFL was achieved for a threshold pump power of 19.9 mW; 2.4- pulses with a repetition rate of 58.5 kHz and maximum single pulse energy of 132 nJ were achieved at a pump power of 139 mW. The obtained results showed the possibility of SNPs serving as a high performance SA for a -switched fiber laser. 收起
