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 microscopeincluding a light source; an acousto-optic deflectorthat deflects ultrashort-pulse laser light L emitted from the light source; an angular-dispersion elementdisposed in front of or after the acousto-optic deflectorthat applies angular dispersion in a direction opposite to the acousto-optic deflectorand a group-velocity-delay dispersion-amount adjusting unitthat adjusts the amount of dispersion compensation by moving the angular-dispersion elementso as to vary the optical path length at each wavelength between the angular-dispersion elementand the acousto-optic deflector
