Abstract:
A solid-state laser comprising an excitation light source, a lens system for focusing an excitation light produced from said light source, and a laser resonator which is laser-oscillated in response to the focused excitation light, wherein said resonator includes only a gain medium and a solid-state medium having dispersion of a wavelength dependence opposite to that of said gain medium, and surfaces of said gain medium and said solid-state medium, which are respectively at opposite sides of opposing surfaces of said gain medium and said solid-state medium, are reflectively coated and act as mirror surfaces, at least one of the other surfaces of said gain medium and said solid-state medium, which are positioned inside said resonator and are opposite to each other, being polished to a curved surface, and wherein an oscillation light is made to enter said solid-state medium at an angle such that the oscillation light is not incident on the curved surface vertically, and said gain medium being excited by said focused excitation light so that the laser oscillation is made in said resonator.
