Abstract

A new nonlinear optical technique is applied to coherent Raman spectroscopy of gases. Two orthogonal pump beams with relative phase modulation are generated in an electro-optic modulator and mixed with a linearly polarized probe. Shot-noise-limited detection and signals linear in either real or imaginary parts of the third-order susceptibility are demonstrated for NO and N₂.
