PROBLEM TO BE SOLVED: To obtain a higher output of excitation laser light. SOLUTION: Ends 15 of a laser medium 19 having light incident/exit surfaces 11, 12 of the laser medium 10 exposed from an excitation chamber 30 is cooled by a gas jet from a gas jet ports 51. Hereby, temperature rise of the laser medium 10 is reduced. COPYRIGHT: (C)2003,JPO |
