Abstract
We propose a novel technique for the generation of high power monocycle terahertz pulse beyond the excitation pulse width limitation. Optical pulse may get modulated by emitted intense THz electric field. This causes excitation pulse compression and consequently gives rise to the enhancement of generation efficiency and its bandwidth. We experimentally demonstrate this chi(2) cascaded processes using tilted wavefront excitation beam by LiNbO3 from Ti:Sapphire and Yb doped fiber laser.
