Abstract
A solid-state laser device, comprising a first resonator arranged on a first optical axis, a second resonator arranged on a second optical axis, a first light emitter for entering an excitation light to the first resonator, a second light emitter for entering an excitation light to the second resonator, and further comprising a separated optical axis portion serving as a part of the first optical axis, a separated optical axis portion serving as a part of the second optical axis, a common optical axis portion where the first optical axis and the second optical axis are superimposed, a first solid-state laser medium arranged on the separated optical axis portion of the first optical axis, a second solid-state laser medium arranged on the separated optical portion of the second optical axis, and an optical member for wavelength conversion and wavelength switching means arranged on the common optical axis portion, wherein the optical member for wavelength conversion comprises a plurality of optical crystals for wavelength conversion having different conversion frequencies, and the wavelength switching means can change the optical crystals for wavelength conversion where a laser beam enters.
