Patent abstract
A mode-locked laser apparatus includes a resonator (laser cavity), a mode-locking device placed in the resonator, a solid-stated laser medium that is doped with Yb (ytterbium) and placed in the resonator and an excitation means for causing excitation light to enter the solid-state laser medium. In the mode-locked laser apparatus, light with an oscillation wavelength in a wavelength band on the longer wavelength side of the maximum peak wavelength in a fluorescence spectrum of the solid-state laser medium is used as output light.
