Abstract

We investigate a compact, stable and broadband multiplex Coherent anti-Stokes Raman Scattering (CARS) source for micro-spectroscopy. By pumping an adapted photonic crystal fiber, we generate the broadband Stokes pulses required for multiplex CARS measurements. The CARS signal stability is provided by an active fiber coupling, avoiding therefore the thermal or mechanical drifts. With only a few nanojoule for pump and Stokes pulses energies, we demonstrate on test liquids the capability of the source to generate multiplex CARS spectra in the 600-2000 cm-1 spectral range.
