论文摘要
我们研究了用商用YB:kgw laser泵送的充满氩气的抗抗抗核心光子晶体纤维中的孤子自我压缩和光电离效应。在光离子化开始之前,我们在一个紧凑的阶段表明我们的220〜FS泵激光自我压缩至13〜fs。通过使用等离子体驱动的孤子自频蓝光,我们还展示了1030至〜700 nm的可调源。我们使用总和生成的时间域Ptychography充分表征了压缩脉冲,从实验中揭示了首次在空心核纤维中的全时质量质量 - 丝岩动力学。
We investigate soliton self-compression and photoionization effects in an argon-filled antiresonant hollow-core photonic crystal fiber pumped with a commercial Yb:KGW laser. Before the onset of photoionization, we demonstrate self-compression of our 220~fs pump laser to 13~fs in a single and compact stage. By using the plasma driven soliton self-frequency blueshift, we also demonstrate a tuneable source from 1030 to ~700 nm. We fully characterize the compressed pulses using sum-frequency generation time-domain ptychography, experimentally revealing the full time-frequency plasma-soliton dynamics in hollow-core fibre for the first time.
