摘要
我们利用商用 Yb:KGW 再生放大器,在紧凑型装置(占地面积为 0.65 m x 2.85 m)中演示了基于两级中空芯光纤压缩技术的亚两周期强激光脉冲的产生。使用一对啁啾镜和一对楔形镜,将第二级中空芯光纤输出功率为 7.2 W 的光谱展宽激光脉冲压缩到 6.6 fs(1030 nm 波长下的 1.9 个周期),效率高达 86%,从而获得 6.2 W 的压缩输出功率。
Sub-two-cycle intense pulse generation based on two-stage hollow-core fiber compression using an ytterbium amplifier
We demonstrate the generation of sub-two-cycle intense laser pulses based on two-stage hollow-core fiber compression in a compact setup (footprint of 0.65 m x 2.85 m) using a commercial Yb:KGW regenerative amplifier. Spectrally broadened laser pulses with an output power of 7.2 W from the second hollow-core fiber stage are compressed down to 6.6 fs (1.9 cycles at 1030 nm) using a pair of chirp mirrors and a pair of wedges with an efficiency of 86%, leading to a compressed output of 6.2 W. A pulse-to-pulse energy stability of 0.26% is measured for 10 minutes.
