We propose and demonstrate a method of suppressing four-wave mixing (FWM) in an optical fiber bundle to realize coherent anti-Stokes Raman scattering(CARS) endomicroscopy, which is the leading candidate for a definitive diagnosis of gastrointestinal cancer. Two excitation laser beams with different wave-lengths are delivered via different cores to suppress FWM and are then combined with a polarization prism and a dual-wavelength waveplate and are focused to a spot. The background emission from the optical fiber bundle was suppressed to 1/3,289, and we demonstrated CARS imaging of a polystyrene bead using the proposed method.
