论文摘要
非线性压缩到几个周期脉冲持续时间的多通细胞被引入，其中包括硅底物上的介电上增强的银镜。在82％的细胞传输下，获得了388 W输出平均功率和776μJ脉冲能量的光谱宽阔。显示了高输出光束质量（M2 <1.2）和高时空谱均匀性（97.5％）以及输出脉冲至6.9 fs持续时间的可压缩性。有限元分析揭示了该单元格至2 kW的平均输出功率。
A multipass cell for nonlinear compression to few-cycle pulse duration is introduced comprising dielectrically enhanced silver mirrors on silicon substrates. Spectral broadening with 388 W output average power and 776 μJ pulse energy is obtained at 82% cell transmission. A high output beam quality (M2<1.2) and a high spatio-spectral homogeneity (97.5%) as well as the compressibility of the output pulses to 6.9 fs duration are demonstrated. Finite element analysis reveals scalability of this cell to 2 kW average output power.
