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 said gain medium being excited by said focused excitation light so that the laser oscillation is made in said resonator.
