A specific scheme is used for fiber delivery of ultrashort pulses using conventional elements. Starting from a standard femtosecond Ti:Al(2)O(3) oscillator (150 fs @ 830 nm), perfectly compressed ultrashort pulses with a duration of 45 fs are produced at the output of a standard two meter long single-mode fiber. The setup allows compensating independently and simultaneously second and third orders of chromatic dispersion as well as management of self-phase modulation in the fiber. It includes an optimized dispersion compensation line made of the assembly of diffraction gratings and prisms. The unsurpassed performances of the device are experimentally and numerically highlighted. Fiber delivery of sub-30 fs multinanojoule pulses is discussed.
采用常规元件进行超短脉冲的光纤传输采用特定方案。从标准的飞秒钛宝石振荡器（150 fs@830nm）开始，在标准的两米长单模光纤的输出端产生持续时间为 45 fs 的完美压缩超短脉冲。该设置允许独立且同时补偿二阶和三阶色散以及光纤中的自相位调制的管理。它包括由衍射光栅和棱镜组件制成的优化色散补偿线。该设备的卓越性能在实验和数值上都得到了强调。讨论了亚 30fs 毫焦脉冲的光纤传输。
