论文摘要
在这项工作中，我们通过基于气体的多通频谱拓宽将1.2秒激光脉冲至13 fs进行压缩。我们的结果产生了一个单阶段的压缩因子，约为200 W平均功率，总压缩因子> 90时降低功率。采用的方案代表了由工业级YB驱动的紧凑型少数周期源的途径：高平均功率的YAG激光器。
In this work, we demonstrate post-compression of 1.2 picosecond laser pulses to 13 fs via gas-based multi-pass spectral broadening. Our results yield a single-stage compression factor of about 40 at 200 W in-burst average power and a total compression factor >90 at reduced power. The employed scheme represents a route towards compact few-cycle sources driven by industrial-grade Yb:YAG lasers at high average power.
