Abstract The frequency‐shifted and pulse‐shaped output of photonic‐crystal fibers (PCFs) pumped by amplified femtosecond Cr:forsterite laser pulses is employed for frequency‐ and time‐resolved four‐wave mixing (FWM) spectroscopy. Cross‐correlation frequency‐resolved optically gated laser‐induced grating (LIG) technique is applied for the characterization of the pulse‐shaped blue‐shifted PCF output. The light pulses produced in the PCF are combined with the second‐harmonic output of the Cr:forsterite laser, to probe a doublet of Raman resonances in the nonlinear response of a test object by means of coherent anti‐Stokes Raman scattering (CARS).
