Ultrashort laser pulses are important driving light sources in the fields of ultrafast optics and high-field laser physics, and can usually be obtained by pulse post-compression methods. This paper introduces in details the development status, principles and related technologies of ultrashort pulses post-compression, including bulk solid material compression, flake group compression, multi-pass cavity compression, hollow waveguide compression, and photonic crystal fiber compression. By summarizing the existing pulse post-compression technology, theoretical guidance is provided for the future research and development direction.
