Compact implementation of Fourier transform two-dimensional IR spectroscopy without phase ambiguity


Helbing, J; Hamm, P (2011). Compact implementation of Fourier transform two-dimensional IR spectroscopy without phase ambiguity. Journal of the Optical Society of America B, 28(1):171-178.

Abstract

We describe an optimized setup for two-dimensional (2D) IR spectroscopy, which can be implemented at low additional cost and with standard optics in any laboratory equipped for femtosecond mid-IR spectroscopy. An interferometer produces a pair of intense pump pulses, whose interferogram is simultaneously recorded and directly yields the relative phase needed for the calculation of absorptive 2D spectra. We analyze different sampling methods based on a realistic noise model and introduce fast population time modulation as an alternative to the use of choppers in the suppression of scatter. Signal levels are compared to those of a photon-echo setup.
