Abstract

We report on nonlinear spectral broadening and post-compression of 1-mJ, 146-fs pulses in a compact single-stage gas-filled multi-pass cell (MPC). With an overall transmission of ~96%, the compressed pulses have a duration of 17.3 fs (corresponding to a compression factor of ~8.4) with 0.96-mJ energy and excellent beam quality (M

$^{2} = 1.35\times 1.12$

). To the best of our knowledge, this work marks the first successful generation of millijoule-level few-cycle pulses at a 1-

$\mu $

m wavelength using a single-stage gas-filled MPC.

用紧凑的单级充气多通道电池产生毫焦耳短周期脉冲

我们报道了在紧凑的单级充气多通道电池（MPC）中1 mj， 146-fs脉冲的非线性谱展宽和后压缩。压缩脉冲的总透射率为~96%，持续时间为17.3 fs（对应于压缩系数为~8.4），能量为0.96 mj，光束质量优良（M $^{2} = 1.35\ × 1.12$）。据我们所知，这项工作标志着使用单级充气MPC在1- $\mu $ m波长上第一次成功地产生了毫焦耳级的短周期脉冲。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
