We present in situ measurements of the relative phase shift induced by Gouy phase shift near the focus in two-color field. The good agreement between the measurement and the theoretical prediction shows that the optimal phase of THz is robust enough as an useful tool to measure the relative phase change.
We experimentally demonstrated that the circularly polarized two-color femtosecond pulses with the same helicity can effectively enhance terahertz intensity by a factor of 5 in comparison with the linearly polarized counterparts. The quantum mechanical simulations confirm this enhancement based on the analysis of residual current calculated by time-dependent Schrödinger equation in three dimensions...
