  The spectral resolution of broadband Fourier-transform coherent anti-Stokes
Raman spectroscopy is limited by the maximum optical path length difference
that can be scanned within a short time in an interferometer. However,
alternatives to the Fourier-transform exist which can bypass this limitation
with certain assumptions. We apply one such approach to broadband coherent
Raman spectroscopy using interferometers with short delay line (low Fourier
spectral resolution) and large delay line (high Fourier spectral resolution).
With this method, we demonstrate broadband coherent Raman spectroscopy of
closely spaced vibrational bands is possible using a short delay line
interferometer, with superior spectral resolution to the longer delay line
instrument. We discuss how this approach may be particularly useful for more
complex Raman spectra, such as those measured from biological samples.
