Dependence of THz time-domain spectroscopy on the crystal thickness and optical width in electro-optic sampling

Abstract:

The processes of electro-optical (EO) sampling of terahertz (THz) pulse were studied theoretically by considering the finite optical probe width and the double-sampling within the same THz pulse. The dependence of THz time-domain waveforms on the crystal thickness and optical width in EO sampling was revealed. Furthermore, the optimal thickness was analyzed, which shows whether or not an antireflection film coated for the optical probe beam is needed.
