| 摘 要： | 报导了一种采用预啁啾管理放大技术实现的百飞秒级掺镱光纤激光器系统。该系统首先利用非线性偏振旋转技术搭建锁模种子激光，实现重复频率为82.3 MHz、压缩后脉宽接近180 fs的近线性啁啾稳定脉冲序列。种子脉冲通过预放大级和预啁啾管理放大级后获得了平均功率为12 W、压缩后脉宽低于100 fs的脉冲。经过预啁啾管理放大级的压缩后脉冲宽度明显优于种子激光的压缩后脉冲宽度。

| Abstract: | This paper reports a 100 fs Yb-doped mode-locked fiber laser based on pre-chirp managed nonlinear amplification. The system was first constructed with the mode-locked seed laser by using the nonlinear polarization rotation technology, which could deliver near-linear chirped stable pulse sequence at a repetition rate of 82.3 MHz. After a pre-amplifier and the pre-chirp managed nonlinear amplifier, the average power of the laser output was boosted over 12 W while the pulse width was reduced to less than 100 fs, effectively improved as a comparison to the 180 fs FWHM of the compressed seed pulse. |
