ABSTRACT:
In a soliton mode-locked solid-state laser apparatus having a resonator which includes therein a solid-state laser medium, a saturable absorption mirror, and a negative group velocity dispersion element, the solid-state laser medium and saturable absorption mirror are disposed in close proximity to each other at a distance not greater than twice a Rayleigh length. Then, the absorption modulation depth ΔR of the the saturable absorption mirror is set to a value not less than 0.4%, and the absolute value |D| (D<0) of a total intracavity dispersion amount D when light having a predetermined wavelength makes one round trip in the resonator, which is represented by the following relational expression, is set within a pulse bandwidth in which operation modes other than a fundamental period soliton pulse can be suppressed by the saturable absorption mirror.τP=1.76⁢D⁢λ0⁢AeffL,4⁢π⁢⁢n2⁢1⁢s⁢1EP
