ABSTRACT:
A scanning laser microscope includes a laser light source; an acousto-optic deflector having a crystal, being arranged in an optical path of a laser beam emitted from the laser light source and capable of changing a traveling direction of the laser beam when frequencies of acoustic waves applied to the crystal are changed; a frequency control unit configured to simultaneously apply acoustic waves having a plurality of frequencies to the crystal of the acousto-optic deflector; an objective lens configured to converge the laser beam emitted from the laser light source to form a beam spot on a specimen; and an optical scanning device configured to two-dimensionally scan the scanning spot by deflecting the laser beam in two directions perpendicular to each other. The acousto-optic deflector, the optical scanning device, and a pupil of the objective lens are arranged at positions optically conjugate with each other.
