PROBLEM TO BE SOLVED: To provide a light excited solid-state laser oscillator which is capable of outputting a high power by a method wherein resonator systems are connected in series. SOLUTION: A light excited soid-state laser oscillator 1 is equipped with a semiconductor laser 9 which functions as an excitation light source to excite a laser medium 3. One of optical elements 13 which concentrate the exciting laser rays 11 emitted from the excitation light source 9 on the laser medium 3 is provided above the laser medium 3, and two of the optical elements 13 are provided below the laser medium 3, that is, a closed exciting optical system is composed of the exciting light source 9 and the three optical elements, and optical elements which are each provided in an upper space above the laser medium 3 and a lower space below the laser medium 3 to form an optical resonator 25 which is provided with an optical axis 27 that extends nearly vertical to the laser medium 3. |
