摘要
随着超快激光脉冲宽度不断变窄,进一步产生单周期乃至亚周期的脉冲面临着巨大的技术挑战。通过脉冲载波包络相位精密控制技术相干合成多路超快光场,不仅是目前超快光学的重要前沿内容,也是实现亚周期脉冲极为有效的方案。结合本课题组近年来在相干合成方面的研究进展,介绍相干合成超快光场的主要技术内容,包括超宽带光谱的产生、色散管理及载波包络相位控制等技术。
Abstract
With the rapid developments of ultrafast lasers toward even shorter pulse, it will suffer great technological and experimental challenges for further generation of optical waveforms with single-cycle or sub-cycle in optical wavelength range. The multi-channel coherent synthesis with precise carrier envelope phase (CEP)-controlled waveforms opens the frontier of ultrafast optics for sub-cycle waveforms generation. In this paper, we review the recent progresses on coherent waveform synthesis based on our research works, the mechanics and key technological approaches are analyzed and discussed, which include ultrabroadband supercontinuum generation, dispersion management and CEP-control.
