Abstract :
We report on terahertz (THz) wave amplification system based on parametric process in Lithium Niobate crystal. We amplified THz wave with the energy of few pJ/pulse to few nJ/pulse. We got maximum amplification factor of more than 1000 for the THz wave with low pulse energy. However the factor decreases with the increase in input pulse energy due to parametric gain saturation of non-linear crystal.
