Abstract
A laser microscope is provided wherein a drop in output power in a positive-dispersion element used as a pulse compressor is reduced, thus improving multiphoton-excitation efficiency. Also, a size of the positive-dispersion element is reduced, thereby making it easier to attach the pulse compressor to a microscope main body and to accommodate the pulse compressor therein, thus improving maneuverability. The invention provides a laser microscope including a laser light source for emitting ultrashort-pulsed laser light; a pulse expander for expanding the ultrashort-pulsed laser light emitted from the laser light source; a large-diameter single-mode fiber for transmitting the ultrashort-pulsed laser light expanded by the pulse expander; a pulse compressor for compressing the ultrashort-pulsed laser light transmitted by the single-mode fiber; and a microscope main body for irradiating a specimen with the ultrashort-pulsed laser light compressed by the pulse compressor.
