A versatile setup for FAST CARS

POSTER

Abstract

We report a versatile setup based on the femtosecond adaptive spectroscopic techniques for coherent anti-Stokes Raman scattering (FAST CARS) $^{[1]}$. We optimize the pulse shape and delay by manipulating the pump/Stokes and probe beams separately using two mirrors in a 4f pulse shaper. Our setup can be easily switched between the collinear single-beam and the noncollinear two-beam configurations without much effort in alignment. We demonstrate the capability for investigating both transparent and highly scattering samples by detecting transmitted and rejected signals, respectively. [1]. Y. Shen, D. V. Voronine, A. V.
