| Research Abstract |
In the present study, we used a new laser source, namely white-light laser source to develop a spectroscopic system which is capable of detecting molecular chirality. First, we employed spectral interferometric technique to improve the sensitivity of the system. As a result, we measured real and imaginary parts of the optical electric field due to the chiral CARS process. Next, we introduced two-color (visible and near infra-red) laser pulses into a photonic crystal fiber in order to extend spectral coverage of the white-light laser. With the use of the visible white-light laser source, we have successfully developed CARS-ROA system in visible, and found improvement of the signal-to-noise ratio.
