Abstract

We propose and demonstrate a coherent anti-Stokes Raman scattering (CARS) spectroscopic fiber probe based on a tapered optical fiber. The fiber probe prepared by the fiber heating fused and tapered method ensures that the output optical power density is high enough to excite the CARS signal. We have been able to detect Raman spectra of various chemical samples. The CARS fiber probe has the potential to achieve high spatial resolution. These results pave the way for flexibility and miniaturization of CARS probes
