Abstract

We present a thulium-doped fiber laser mode-locked by a carboxymetylcellulose high-optical quality film with dispersed single-walled carbon nanotubes. Laser system based on the nonlinear amplifying loop mirror generates the shortest pulses earlier obtained in SWCNT mode-locked thulium-doped fiber lasers with a duration of 450 fs and 18 mW maximum average power at 1870 nm.

摘要

我们展示了一种由含有分散单壁碳纳米管的羧甲基纤维素高光学质量薄膜锁模的掺铥光纤激光器。基于非线性放大环镜的激光系统产生了在掺铥光纤激光器中通过单壁碳纳米管锁模较早获得的最短脉冲，脉冲持续时间为450飞秒，在1870纳米处最大平均功率为18毫瓦。
