Abstract:
In multiplex CARS, a fingerprint region is a region where signals are densely concentrated. Information about the intensities and spatial distribution of these signals is important in cell analysis. However, there has been a problem in that the signal intensities are low. Accordingly, mechanisms 702 and 703 for adjusting the power branching ratio between light that enters a photonic crystal fiber 705 and pumping light; mechanisms 710 and 711 for adjusting the divergence/convergence state of the pumping light; and mechanisms 706 and 2101 for adjusting the divergence/convergence state of Stokes light are provided to enable adjustment for emphasizing a desired wavelength band.
