本文采用金纳米颗粒辅助气液固法制备了磷化铟（InP）纳米线，并将其用作Yb：KYW体激光器的可饱和吸收体。利用I扫描方法对所制备的InP纳米线SA的饱和吸收特性进行了表征。获得了394fs的超短脉冲，重复频率为41.5MHz，最大平均输出功率为315mW。据我们所知，这是第一次演示的InP纳米线作为SA的飞秒脉冲产生的固体激光器。结果表明，InP纳米线是一种很有前途的超快光子器件应用的SA候选人。
In this letter, indium phosphide (InP) nanowires (NWs) are fabricated by Au-nanoparticle assisted vapor-liquid-solid method and applied as a saturable absorber (SA) for continuous-wave (CW) mode-locked femtosecond Yb:KYW bulk laser. I-scan method was used to characterize the saturable absorption properties of the prepared InP NWs SA. Pulses as short as 394 fs with the repetition rate of 41.5 MHz and maximum average output power of 315 mW are achieved. To the best of our knowledge, this is the first demonstration of InP NWs working as SA for the fs-pulse generation in the solid-state bulk laser. The results indicate that InP NWs are a promising SA candidate for applications in ultrafast photonic devices.
