Abstract :
The terahertz Kerr effect and terahertz induced optical second harmonic generation from the surface of different materials were investigated using intense THz pulses. Terahertz Kerr nonlinear coefficients and relaxation times for several liquids were measured. The significant increase of the optical second harmonic signal when strong THz field was applied were demonstrated and discussed theoretically.
