Modulation of Terahertz Generation in Two-color Photoionization Verified by the Spectral Broadening

Not Accessible

Abstract

We studied the evolution of the two-color laser filament emitted THz pulse energy with the influences of the infrared pump energy and air dispersion. The THz modulation induced by additional relative phase is verified by the two-color spectral broadening due to the intensity dependent nonlinearity.
