Abstract
A laser microscope comprises a laser light source emitting illumination light; an objective applying the illumination light on a sample; a light path compounding unit compounding a first illumination light path and a second illumination path between the laser light source and the objective; a phase-modulation type spatial light modulator placed on a position on the first illumination path, the position also being optically conjugate with a pupil position of the objective, modulating a phase of the illumination light; and a two-dimensional scanning unit placed on the second illumination light path, scanning the sample in a plane orthogonal to an optical axis of the objective.
