Abstract :
We present our results on THz pulse generation in the 0.1-2.5 THz band via optical rectification of femtosecond laser pulses in a tapered crystal. A simulation study for visualization of THz wave propagation in the crystal has been performed. It is shown that the mode structure and phase velocity of the THz wave in the crystal are changed.
