<P>PROBLEM TO BE SOLVED: To provide a laser oscillation device which can be simplified and ensures stable radiation of a laser beam. <P>SOLUTION: A laser surgery apparatus 1 includes: a laser oscillator 3, having an excitation light source 14 and a laser medium 13; a capacitor 5 for supplying power to the excitation light source by discharging; a cooling means 4 for cooling the laser oscillator by circulating a coolant; a heater 6 for heating the coolant of the cooling means; a power source 7 for supplying power to the capacitor and the heater; and a heater switch means S2 which causes the heater to energize the power source or capacitor. When the heater switch has the power source supply power to the heater, the heater heats the coolant; and when the capacitor supplies power to the heater, the heater causes the capacitor to discharge electric charges. <P>COPYRIGHT: (C)2010,JPO&INPIT |
