Abstract Based on an as-prepared high-quality tin diselenide-polyvinyl alcohol (SnSe2-PVA) film, a stable passively erbium-doped (Er-doped) soliton mode-locked fiber laser at 1561.38 nm was realized. The output performances were investigated experimentally. At the pump power of 310 mW, the shortest pulse duration of 1.197 ps was obtained with a fundamental frequency of 3.45 MHz, corresponding to the peak power of 317 W, which is much higher than previous reports of SnSe2 mode-locked fiber lasers. The results show that SnSe2 can offer an exciting platform for stable high peak power and ultrashort pulse generation.

基于 SnSe2 的锁模光纤激光器产生稳定的孤子脉冲

摘要 基于所制备的高质量二硒化锡-聚乙烯醇（SnSe2-PVA）薄膜，实现了一种稳定的1561.38 nm被动掺铒（Er掺杂）孤子锁模光纤激光器。实验研究了输出性能。在 310 mW 的泵浦功率下，以 3.45 MHz 的基频获得了 1.197 ps 的最短脉冲持续时间，对应于 317 W 的峰值功率，这远高于先前关于 SnSe2 锁模光纤激光器的报道。结果表明，SnSe2 可以为稳定的高峰值功率和超短脉冲产生提供一个令人兴奋的平台。
