Abstract
Hybrid fs/ps coherent anti‐Stokes Raman scattering is a recent nonlinear optical technique where interaction of a Raman medium with simultaneous femtosecond (fs) pump and Stokes pulses is interrogated by means of a delayed picosecond (ps) probe. The resulting anti‐Stokes signal is usually studied by means of numerical methods built on the conventional time‐dependent model of Raman coherence. Here, we suggest that, in place of numerical tools, the time model is in complete analogy with an earlier frequency‐dependent analytical model and can be equally treated to a great extent despite the complications arising from probe pulses of non‐trivial time shapes. To verify the reliability of this approach, closed‐form solutions to the time model are compared to published experimental results. In addition to fast signal reconstruction, adequate spectral accuracy is demonstrated. Copyright © 2017 John Wiley & Sons, Ltd.
