论文摘要
我们通过压缩kHz Ti：蓝宝石激光器在大孔长的长空心纤维中的压缩来报告6.1 MJ，3.8 FS脉冲的产生。为了找到高脉冲能在高脉冲能量下的光谱扩展的最佳条件，我们探索了不同参数范围，而电离或KERR效应主导的情况。确定最佳参数设置后，获得高波导传输处的较大光谱拓宽。强烈的1.5周期脉冲用于氩和霓虹灯的高谐波产生。
We report on the generation of 6.1 mJ, 3.8 fs pulses by the compression of a kHz Ti:sapphire laser in a large-aperture long hollow fiber. In order to find optimal conditions for spectral broadening at high pulse energies, we explore different parameter ranges where ionization or the Kerr effect dominates. After identifying the optimum parameter settings, large spectral broadening at high waveguide transmission is obtained. The intense 1.5-cycle pulses are used for high-harmonic generation in argon and neon.
