Abstract

We present a polarization method that significantly improves the signal-to-noise ratio in two-dimensional (2D) spectra collected in a "pump-probe" phase-matching geometry by improving the signal strength and eliminating unwanted background signals. This beam geometry is particularly useful when collecting 2D spectra using a pulse shaper.
