SOLAR LIGHT PUMPED LASER AND COOLING SYSTEM OF SOLAR LIGHT PUMPED LASER

摘要

[PROBLEMS] To provide a solar light pumped laser and its cooling system. [MEANS FOR SOLVING PROBLEMS] The solar light pumped laser (10) performing laser oscillation by pumping a laser medium with solar light, comprises the laser medium (12), a containing device (14) that supports the laser medium (12) internally and is provided with a condensing optical element (22) for irradiating solar light condensed along the laser medium (12) while holding cooling liquid in a space between the laser medium (12) and the containing device (14), and a pair of optical reflection elements (16,18) arranged contiguously to the opposite ends of the laser medium (12). End of the containing device (14) has Brewster's angle. The cooling liquid contains water that functions as an optical medium to form a water lens and, at the same time, cleans the condensing optical element (22).
