Optimization of electro-optical sampling of THz pulse with a chirped broadband probe pulse in thick EO crystal

Electrooptic (EO) sampling is a method in THz time-domain spectroscopy. In previous studies, a thick EO crystal with a broadband probe pulse is used to meet the requirements of THz detection with a large time window and high-precision frequency spectrum. However, the broadband probe pulses are significantly broadened in the time domain during the transmission in thick EO crystals due to group velo...
