We report the experimental results on generating pulsed terahertz (THz) radiation, frequency-tunable within the range 0.5−2 THz. The THz pulse generation was implemented using the method of optical rectification of femtosecond laser pulses in the nonlinear organic crystal OH1. The frequency tuning of the THz radiation was provided by adaptive phase – amplitude modulation of the pump pulses from the Cr : forsterite laser system with a radiation wavelength of 1230 nm using the acoustooptical dispersion delay line.
