We present directly oscillator-driven self-compression inside an all-bulk Herriott-type multi-pass cell in the near-infrared spectral range. By utilizing precise dispersion management of the multi-pass cell mirrors, we achieve pulse compression from 300 fs down to 31 fs at 11 µJ pulse energy and 119 W average power with a total efficiency exceeding 85%. This corresponds to an increase in peak power by more than a factor of three and a temporal compression by almost a factor of ten in a single broadening stage without necessitating subsequent dispersive optics for temporal compression. The concept is scalable towards millijoule pulse energies and can be implemented in visible, near-infrared and infrared spectral ranges. Importantly, it paves a way towards exploiting Raman soliton self-frequency shifting, supercontinuum generation and other highly nonlinear effects at unprecedented high peak power and pulse energy levels.

在 1 µm 波长处在全体积多通道几何结构中进行自压缩

我们在近红外光谱范围内的全散装 Herriott 型多通道单元内直接呈现振荡器驱动的自压缩。通过利用多通道单元镜的精确色散管理，我们在 11 µJ 脉冲能量和 119 W 平均功率下实现了从 300 fs 到 31 fs 的脉冲压缩，总效率超过 85%。这对应于在单个展宽阶段中峰值功率增加超过 3 倍，时间压缩几乎是 10 倍，而无需后续的色散光学器件进行时间压缩。该概念可扩展至毫焦耳脉冲能量，并可在可见光、近红外和红外光谱范围内实施。重要的是，它为利用拉曼孤子自频移铺平了道路，
