Abstract

We fabricated a fiber-connector-type saturable absorber in which SWNTs and P3HT (poly-3-hexylthiophene) were coated on the fiber connector end. This saturable absorber allowed us to realize a short laser cavity length. We used a soliton cavity configuration to generate the shortest pulse (147 fs) at the highest repetition rate (51 MHz) yet obtained with carbon nanotubes (CNT) related saturable absorbers.

摘要

我们制造了一种光纤连接器型可饱和吸收体，其中单壁碳纳米管（SWNTs）和聚3 - 己基噻吩（P3HT）被涂覆在光纤连接器端部。这种可饱和吸收体使我们能够实现短激光腔长度。我们采用孤子腔配置，以与碳纳米管（CNT）相关的可饱和吸收体所获得的最高重复频率（51 MHz）产生了最短脉冲（147飞秒）。
