Abstract

We examine the generation of terahertz (THz) by optical rectification of a fundamental infrared beam with its first harmonic in ionized air. From polarization measurements we identify an important, yet so far unreported (to our knowledge), cross term (χ_xyxy ⁽³⁾+χ_xyyx⁽³⁾) of the nonlinear susceptibility tensor. Omission of this term leads to an error by a factor of 10⁶ of the THz intensity obtained with certain polarization configurations.
