Abstract
Ultrahigh intensity lasers have been excellent tools in exploring the physics of superintense laser-matter interactions. The laser power has increased steadily to a multi-PW level by implementing the chirped pulse amplification (CPA) technique. Such a laser power can be further enhanced through a pulse shortening without additional the amplifiers. To enhance a peak power of a high energy femtosecond laser, the pulse shortening was investigated through a post-compression by installing a post-compression stage of a 100-TW CPA laser. The laser spectrum was broadened by the self-phase modulation (SPM) in thin fused silica plates and an induced dispersion was compensated by a set of chirped mirrors. The laser beam was post-compressed from 23 fs to 9.7 fs, corresponding to the peak-power enhancement by a factor of 2.1.
