Abstract:
There is provided a mode-locked laser device including: a resonator; a solid-state laser medium that is disposed in the resonator and outputs oscillation light in accordance with the incidence of excitation light; a saturable absorber that is disposed in the resonator and induces soliton mode-locking; a group velocity dispersion correction component that is disposed in the resonator and controls group velocity dispersion in the resonator; and an excitation portion that causes excitation light to be incident at the solid-state laser medium, wherein a resonator length of the resonator is at least a resonator length with which soliton mode-locking is inducible and is less than a resonator length with which non-soliton mode-locking is inducible.
