Abstract
The capabilities of a Coherent anti-Stokes Raman scattering (CARS) microscopy technique that utilizes a commercially available microstructured-fibre for the generation of a Stokes supercontinuum, largely depend on the spectral characteristics of the fibre itself. Such fibres, however, have notoriously limited spectral powers and wavelength coverage, thus limiting the excitation efficiency of fibre-based CARS. We demonstrate that through the combination of time-gating and systematic power-tuning of the input pulse into a supercontinuum-generating fibre—a process we term “spectral surfing”—we are able to extend and bolster the excitation efficiencies of spectral-focusing CARS hypermicroscopy across the vibrational spectrum from ~300 cm-1 to >3500 cm-1.
