Abstract

We demonstrate a comprehensive characterization of the diode-pumped Yb:BiSiO laser operating in the continuous-wave and soliton mode-locked regimes. Pumping with a 650 mW, single-transverse mode, fiber-coupled laser diode, a maximum continuous-wave output power amounted to 213 mW with a slope efficiency up to 57.6%. A broadband wavelength tuning range of more than 70 nm was achieved in CW regime with a fused silica prism. Applying a SESAM as mode locker, nearly transform-limited pulses as short as 113 fs were generated for a maximum average power of 53 mW and a pulse repetition rate of ∼106 MHz. To the best of our knowledge, this is the first report on passively mode-locked operation with the Yb:BiSiO crystal.

摘要

我们展示了对在连续波和孤子锁模状态下工作的二极管泵浦Yb:BiSiO激光器的全面表征。用一个650 mW的单横模光纤耦合激光二极管泵浦时，最大连续波输出功率达到213 mW，斜率效率高达57.6%。在连续波状态下，使用熔石英棱镜实现了超过70 nm的宽带波长调谐范围。应用SESAM作为锁模器，在最大平均功率为53 mW和脉冲重复率约为106 MHz的情况下，产生了短至113 fs的近变换极限脉冲。据我们所知，这是关于Yb:BiSiO晶体被动锁模运行的首次报道。
