Abstract:
1. An optical microscope for collecting, on a sample, stimulation light emitted from a stimulation light source and having a single wavelength or a plurality of different wavelengths, and for detecting response light emitted from the sample in a nonlinear optical response process, the microscope comprising: an erase light source for emitting erase light having a wavelength different from that of the stimulation light and inducing an effect of suppressing secondary response light which appears due to irradiation of the stimulation light on the sample, an optical system configured to simultaneously irradiate the erase light and the stimulation light on the sample such that the erase light does not suppress the response light emitted from a light-collecting area of the stimulation light but suppresses only the secondary response light other than the response light emitted from the light-collecting area of the stimulation light, and an optical element which adjusts a light-collecting position of the erase light and which enables irradiation of the erase light to a position that is three-dimensionally independent from a light-collecting position of the stimulation light such that only the secondary response light is suppressed.
