Abstract

Abstract High-performance 86 μJ, 11.2 fs pulses with a spectrum range of 800–1050 nm are generated based on 1030 nm, 190 fs Yb femtosecond pulses by using multi-plate-based spectral broadening and filtering. Taking advantage of single beam configuration, the obtained pulses have excellent power and spectral stabilities. Since the output spectrum is obtained by spectrally filtering the broadened components, the temporal contrast of the output pulses is enhanced by at least four orders of magnitude. Together with the robust and simple setup, the proposed method is expected to be a competitive option for the generation of seed pulses for 10s–100s petawatt lasers.

基于光谱展宽和滤波的高性能800-1050 nm种子脉冲

摘要以1030 nm、190 fs的Yb飞秒脉冲为基础，采用多片谱展宽滤波技术，产生了光谱范围为800 ~ 1050 nm的高性能86 μJ、11.2 fs脉冲。利用单光束结构，获得的脉冲具有优异的功率和光谱稳定性。由于输出光谱是通过对加宽分量进行频谱滤波得到的，因此输出脉冲的时间对比度至少提高了4个数量级。结合鲁棒性和简单的设置，所提出的方法有望成为10s-100s佩瓦激光器产生种子脉冲的竞争性选择。
