Bloem, R; Garrett-Roe, S; Strzalka, H; Hamm, P; Donaldson, P M (2010). Enhancing signal detection and completely eliminating scattering using quasi-phase-cycling in 2D IR experiments. Optics Express, 18(26):27067-27078.
We demonstrate how quasi-phase-cycling achieved by sub-cycle delay modulation can be used to replace optical chopping in a box-CARS 2D IR experiment in order to enhance the signal size, and, at the same time, completely eliminate any scattering contamination. Two optical devices are described that can be used for this purpose, a wobbling Brewster window and a photoelastic modulator. They are simple to construct, easy to incorporate into any existing 2D IR setup, and have attractive features such as a high optical throughput and a fast modulation frequency needed to phase cycle on a shot-to-shot basis.
