超短脉冲UV在空芯光子晶体光纤中的高效自压缩

Efficient self-compression of ultrashort UV pulses in air-filled hollow-core photonic crystal fiber

Jie Luan, Philip St. J. Russell, David Novoa

摘要:

报道了在空气填充的Kagomé型空芯光子晶体光纤中利用孤子自压缩产生超短紫外光脉冲。在400 nm处能量为2.6 μ J、持续时间为54 fs的泵浦脉冲在时间上被压缩了5倍,持续时间为~11 fs。实验结果得到了数值模拟的支持,表明Raman和Kerr效应在压缩动力学中起着重要作用。使用环境空气的便利性,以及没有会使压缩脉冲失真的玻璃窗,使得该设置作为高效桌面UV脉冲压缩器的基础非常有吸引力。

英文摘要:

We report generation of ultrashort UV pulses by soliton self-compression in kagomé-style hollow-core photonic crystal fiber filled with ambient air. Pump pulses with energy 2.6 uJ and duration 54 fs at 400 nm were compressed temporally by a factor of 5, to a duration of ~11 fs. The experimental results are supported by numerical simulations, showing that both Raman and Kerr effects play a role in the compression dynamics. The convenience of using ambient air, and the absence of glass windows that would distort the compressed pulses, makes the setup highly attractive as the basis of an efficient table-top UV pulse compressor.
