Abstract:
1. A laser microscope comprising: a first laser light source which emits first illumination light; a second laser light source which emits second illumination light; an objective which applies the first illumination light and the second illumination light on a sample; a light path compounding unit which compounds a first illumination light path of the first illumination light and a second illumination light path of the second illumination light; a phase-modulation type spatial light modulator which (i) is placed at a position on the first illumination light path between the first laser light source and the light path compounding unit, (ii) modulates a phase of the first illumination light, and (iii) is one of a reflection-type liquid crystal phase modulator, a transmission-type liquid crystal phase modulator, and a reflection-type mirror phase modulator, wherein the position of the spatial light modulator is optically conjugate with a pupil position of the objective; a two-dimensional scanning unit which is placed on the second illumination light path between the second laser light source and the light path compounding unit, and which scans the sample in a plane orthogonal to an optical axis of the objective; a first relay optical system which relays a pupil of the objective to a first position between the light path compounding unit and the phase-modulation type spatial light modulator; and a second relay optical system which relays the pupil relayed to the first position by the first relay optical system to the phase-modulation type spatial light modulator.
