Abstract
We show measurements and simulations of difference-frequency generation of THz pulses and subsequent free-space electro-optic sampling with prechirped femtosecond pulses in ZnTe. Negative prechirping enhances the efficiency due to compression of the laser pulse in the dispersive nonlinear crystal.
