Abstract

We report on a mode-locked fiber laser featuring an Yb-doped large-mode-area Bragg fiber and exploiting dissipative-soliton pulse shaping. Reliable self-starting mode-locking is achieved using a fast semiconductor saturable absorber mirror. The laser generates 30 nJ chirped pulses at 17 MHz repetition rate for an average power of 510 mW. The 3.2 ps output pulses are compressed outside the cavity to 440 fs.

摘要

我们报告了一种基于掺镱大模场面积布拉格光纤的锁模光纤激光器，该激光器利用耗散孤子脉冲整形技术。采用快速半导体可饱和吸收镜实现了可靠的自启动锁模。该激光器在 17 MHz 的重复率下产生 30 nJ 啁啾脉冲，平均功率为 510 mW。3.2 ps 的输出脉冲在腔外压缩到 440 fs。
