PURPOSE:To obtain a subminiature harmonics conversion device simplified in structure and lessened in number of parts by a method wherein a solid laser medium possessed of self-harmonics converting function is utilized. CONSTITUTION:A solid laser medium 1 possessed of self-harmonics converting function, a lens 2, and a semiconductor laser chip 3 are housed in the same package, and the end faces 1A and 1B of the solid laser medium constitute an optical resonator. Laser rays emitted from a semiconductor laser 3 are condensed through the lens 2 to excite the end faces of the solid laser medium 1 in an axial direction. By the setup, a subminiature stable solid-state laser formed in an integral structure can be obtained and reduced in number of parts by using a solid laser medium possessed of self-harmonics converting function. |
