摘 要 | 通过对激光脉冲频谱的相位、振幅或偏振进行调制,可以获得不同时域分布的激光脉冲。这些特性不同的激光脉冲在物理过程和光学器件研究中具有重要的应用。随着光发射电子显微镜、超灵敏探测光谱仪、扫描近场显微等技术的发展,激光脉冲整形技术在微纳米光学中的应用日益深入。总结了近年来激光脉冲整形与测量技术的发展,综述了激光脉冲整形在近场光学、光发射电子显微镜、单分子光谱中的应用研究进展。

Abstract | An ultrashort laser pulse will own different characteristic time distribution when its phase, amplitude or polarization is modulated in the frequency domain. These characterized ultrashort laser pulses are applied in the research of basic physical processes and optical devices. Benefiting from the development of photoemission microscopy, ultrasensitive spectroscopy and scanning near-field optical microscopy, the ultrashort laser pulse shaping technique has been more and more applied in micro- and nano-optics. This review summarizes the development of ultrashort laser pulse shaping and characterizing techniques and the usage of the ultrashort laser pulse shaping technique in scanning near-field optical microscopy, photoemission electron microscope and single molecule spectroscopy.
