Abstract
To measure homodyne interference with a CARS microscope, a supercontinuum beam is used as a light source. A supercontinuum beam is generated using a nonlinear optical fiber that has normal dispersion in which the coherence between pulses is maintained. As the phases of the interference components of detected beams are the same between pulses, it is possible to integrate the interference components and thus improve the signal-noise ratio.
