  We demonstrate low-frequency interferometric impulsive stimulated Raman
scattering (ISRS) imaging with high robustness to distortions by optical
scattering. ISRS is a pump-probe coherent Raman spectroscopy that can capture
Raman vibrational spectra. Recording of ISRS spectra requires isolation of a
probe pulse from the pump pulse. While this separation is simple in
non-scattering specimens, such as liquids, scattering leads to significant pump
pulse contamination and prevent the extraction of a Raman spectrum. We
introduce a robust method for ISRS microscopy that works in complex scattering
samples. High signal-to-noise ISRS spectra are obtained even when the pump and
probe pulses pass through many scattering layers.
