Abstract:
1. 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, wherein: 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, wherein said Rayleigh length is obtained on the basis of beam waist diameter at the saturable absorption mirror; the saturable absorption mirror has an absorption modulation depth ΔR not less than 0.4%; and the absolute value |D| of a total intracavity linear 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 range of minimum value 0 to maximum value which is calculated from pulse bandwidth Δλ (where, c is the velocity of light, λ
