Abstract :
Efficiency of terahertz electro-optic sampling in a number of II-VI, III-V and III-VI crystals have been experimentally compared and analyzed. The terahertz pulses generated in femtosecond laser plasma filament were electro-optically detected in the crystals under investigation and recorded using conventional THz-TDS setup. Influence of crystal natural properties and chemical compound on the recorded spectra is discussed. In particular, influence of sulfur concentration in GaSe1-xSx mixed crystals on efficiency of terahertz detection was tested.
