ABSTRACT:
A laser microscope according to the present invention is characterized by comprising a laser light source configured to emit an ultra-short pulse laser beam, a storage unit configured to store at least one of dispersion data and chirp amounts of a plurality of optical members inserted in an optical path, a pulse width adjuster configured to adjust a pulse width of the ultra-short pulse laser beam, and a controller configured to control the pulse width adjuster based on at least one of the dispersion data and the chirp amounts of at least one of a laser wavelength of the laser light source and at least one optical member so that the pulse width is shortened on a sample surface.
