摘要
提出了一种很有特色的基于超连续谱注入的飞秒光参量放大技术,该种技术方法不仅克服了常规1 053 nm脉冲在前端小能量放大时的增益窄化现象,而且可实现800 nm激光和1 053 nm激光的零时间同步。通过系统的实验研究,获得了大于4 mJ的1 053 nm宽带信号光能量。
Based on supercontinuum injection, a new method of high-energy fem,osecond parametric amplification is put forward. The method overcomes the gain narrowing effect of the conventional 1 053 nm low-energy amplification and realizes the synchronization between 800 nm and 1 053 nm laser pulses. Through systematic experimental investigation, a broadband 1 053 nm laser pulse is obtained, with energy exceeding 4 mJ ,which is the maximum energy obtained directly through a femtosecond OPA in the world.
