Abstract
In a multi-color CARS microscope, it has been difficult to accurately bring optical axes of pump light and Stokes light into correspondence and to stably acquire a spectral signal. Accordingly, in an optical analysis device, CARS light is generated from, a sample by using a residual component of the pump light introduced to an optical waveguide and the Stokes light generated in an optical waveguide.
