Photonic‐crystal fibers deliver frequency‐tunable radiation within the wavelength range stretching from the ultraviolet to the near‐infrared with output pulse widths from tens of femtoseconds to a few picoseconds and peak powers from a few watts to several megawatts, suggesting a convenient, efficient, and compact fiber format of short‐pulse sources for time‐resolved nonlinear spectroscopy and microscopy. Here, we examine the potential of photonic‐crystal fiber light sources for time‐resolved studies of ultrafast population and coherence relaxation dynamics in molecular systems using coherent anti‐Stokes Raman scattering and two‐photon‐resonant sum‐frequency generation.
