Abstract
It is an object to perform high-precision observation by compensating group-velocity-delay dispersion and angular dispersion with a simple structure. The invention provides a laser microscope 1 including a light source; an acousto-optic deflector 7 that deflects ultrashort-pulse laser light L emitted from the light source; an angular-dispersion element 8, disposed in front of or after the acousto-optic deflector 7, that applies angular dispersion in a direction opposite to the acousto-optic deflector 7; and a group-velocity-delay dispersion-amount adjusting unit 10 that adjusts the amount of dispersion compensation by moving the angular-dispersion element 8 so as to vary the optical path length at each wavelength between the angular-dispersion element 7 and the acousto-optic deflector 8.
