摘 要: | 利用低温工作状态下Yb∶YAG再生放大器,对1030nm光纤锁模激光器输出的250pJ的种子光进行放大。电光开关门宽控制种子光在放大器内20程往返,最大单脉冲能量为217μJ,输出频率10Hz,同时由于其增益窄化效应光谱宽度由8.9nm减小到0.3nm,相应的脉宽由18.0ps被压缩到5.5ps,这与理论模拟结果的0.4nm,4.2ps基本吻合。实验结果论证了采用窄增益带宽的再生放大器可以同时实现亚皮秒光参量啁啾脉冲放大(OPCPA)对抽运脉冲宽度和光谱宽度的要求,避免使用光纤光栅对光谱滤波带来的高阶非线性效应。

Abstract: | A 250 pJ seed pulse from 1030 nm fiber mode-locked laser is amplified by cryogenic Yb:YAG regenerative amplifier. After the seed pulse is amplified by 20 circles by controlling the electro-optical switch, the max single pulse energy is 217 μJ, the output rate is 10 Hz. Meanwhile, the spectrum decreases from 8.9 nm to 0.3 nm for gain narrowing, the corresponding pulse width is compressed from 18.0 ps to 5.5 ps, which fits the simulated result of 0.4 nm and 4.2 ps. The experimental result demonstrates that regenerative amplifier using gain narrowing can realize the require for pump pulse width and spectrum width of subpicosencond optical parametric chirped pulse amplification (OPCPA), and avoid high order nonlinear effect by fiber grating. |
