An optical apparatus using DCARS(Depletion Coherent Anti-Stokes Raman Spectroscopy) is provided to secure spatial resolving power below a diffraction limit by utilizing the DCARS adopting a laser beam of a doughnut mode, and to measure a sample without influence on the sample. An optical apparatus(100) using DCARS for observing a sample after expanding a micro part of the sample by irradiating the light to the sample is composed of a first optical device for generating the depletion light; a second optical device for generating the anti-stroke light; an optical system for mixing the depletion light and the anti-stroke light and then irradiating the mixed light to the sample; and a detector(190) for detecting the light reflected from the sample. |
