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

Z-scan curves (colored) obtained through the numerical simulation of the method (see Methods) for (a) 1 and 10T0 and (b) 0.3T0 pulses for the central wavelength λ0 = 0.3 mm and crystal thickness of 0.3 mm; black curve corresponds to the analytical model for monochromatic THz radiation.
