Abstract :
The results of the THz pulse generation via optical rectification of pico- and femtosecond laser pulses in nonlinear crystal are presented. Detection of THz pulse are performed at room temperature by both Schottky diode and ZnTe crystal. The quantum efficiency of energy conversion up to 28 % of maximum value is obtained with Schottky diode.
