ABSTRACT:
A solid-state laser having a laser resonator which includes an etalon to allow a single longitudinal mode of oscillation to occur in the width of the wavelength which permits the oscillation of the medium of the solid-state laser. The etalon is interposed in the resonator which is constituted of a surface of a resonant mirror and one end surface of a solid-state laser medium, and wherein the interval of the longitudinal modes of the etalon is set to be in the range from approximately one half to one width of the oscillation wavelength of the medium of a solid-state laser. At the same time, the ratio, with respect to the optical length, of the etalon to the resonator is selected to be about a half integer.
