Abstract
© 2022 Optica Publishing Group.We demonstrated sub-10 fs pulse generation by the post-compression of a 100 TW Ti:Sapphire laser to enhance the peak-power. In the post-compression, the laser spectrum was widely broadened by self-phase modulation in thin fused silica plate(s), and the induced spectral phase was compensated with a set of chirped mirrors. A spatial filter stage, consisting of two cylindrical lenses and a spherical lens, was employed to reduce the intensity modulation existing in the laser beam, which effectively suppressed intensity spikes induced by self-focusing. The laser beam was post-compressed from 23 fs to 9.7 fs after propagating through a 1.5mm fused silica plate, resulting in the peak-power enhancement by a factor of 2.1.
