摘要：
A new electro-optic (EO) sampling scheme, which we refer to as "heterodyne EO sampling," for the detection of pulsed terahertz (THz) waves is proposed and demonstrated. In this heterodyne EO sampling scheme, the intensity change in the sampling optical pulse induced by a THz field in a nonlinear crystal is measured without using any polarization optics. Applied in conjunction with the noncollinear Cherenkov phase matching technique, this method allows efficient and easy detection of pulsed THz wave using a simpler optical setup than in the conventional EO sampling method.
