We demonstrate a 1.5 microm passively mode-locked fiber laser using an intersubband transition (ISBT) in a quantum well as a saturable absorber. The saturable absorption characteristic of faster than 1 ps in the ISBT was utilized for femtosecond pulse generation. We designed the laser cavity as a soliton laser, which enabled us to generate a stable pulse. As a result, an 88 fs, 42 MHz soliton pulse was successfully generated.
我们展示了一种1.5微米的被动锁模光纤激光器，它使用量子阱中的子带间跃迁（ISBT）作为可饱和吸收体。利用ISBT中快于1皮秒的可饱和吸收特性来产生飞秒脉冲。我们将激光腔设计为孤子激光器，这使我们能够产生稳定的脉冲。结果，成功产生了一个88飞秒、42兆赫兹的孤子脉冲。
