摘要
啁啾脉冲放大技术是高功率飞秒脉冲光纤激光器采用的主流技术,但如果对激光系统中非线性效应和色散补偿控制不好,脉冲将会发生畸变,影响脉冲的进一步压缩和峰值功率的提高。以这些问题的解决为主线,介绍了近年来在高功率飞秒脉冲研制上所取得的进展,指出以光子晶体光纤等为基础的新型激光功能器件的出现,为啁啾脉冲放大技术提供了新的解决方案。
Chirp pulse am Dlification technology of is critical for fabrication of high Dower femtosecond fiber laser. However. if the nonlinearity and the compensation of disperslor7 are not well controlled, the quality of pulse will degrade and it will hamper the further compression and the improvement of power. To solve these problems, research on high power femtosecond fiber laser has been carried out. The appearance of new functional components based on photon crystal fiber provides new ways to the technology of chirp pulse amplification.
