Methodical inaccuracy of the Z-scan method for few-cycle terahertz pulses

Abstract Modern sources of THz radiation generate high-intensity pulses allowing to observe nonlinear effects in this spectral range. To describe many nonlinear effects theoretically, it is necessary to know the nonlinear refractive index coefficient of optical materials. The work studies the applic...
