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 microscope1including a light source; an acousto-optic deflector7that deflects ultrashort-pulse laser light L emitted from the light source; an angular-dispersion element8,disposed in front of or after the acousto-optic deflector7,that applies angular dispersion in a direction opposite to the acousto-optic deflector7;and a group-velocity-delay dispersion-amount adjusting unit10that adjusts the amount of dispersion compensation by moving the angular-dispersion element8so as to vary the optical path length at each wavelength between the angular-dispersion element7and the acousto-optic deflector8.
