Fluorescence generated by multiphoton excitation can be observed simultaneously using multiple beams, and multiple points can be observed simultaneously with a high signal-to-noise ratio with low invasiveness. Provided is a laser microscope 1 including: modulation units 5 and 6 that apply different modulations to a plurality of ultrashort-pulse laser light beams of the same type emitted from a light source unit 3; an illumination optical system 7 that simultaneously focuses the plurality of ultrashort-pulse laser light beams, to which the different modulations are applied by the modulation units 5 and 6, onto different positions of a sample O; a fluorescence detecting device 8 that detects fluorescence generated at a focal position of each ultrashort-pulse laser light beam and performs photoelectric conversion of the fluorescence; and a demodulation unit 9 that demodulates an output from the fluorescence detecting device 8 based on modulation information from the modulation units 5 and 6. |
