PROBLEM TO BE SOLVED: To provide a laser oscillation device with a laser medium gas replacement function capable of optimizing time-restriction of an operator, a laser medium gas or the quantity of electricity as an exciting energy source even after the laser oscillation device in not-operation state.SOLUTION: When exciting power dispersion>dispersion upper limit, a laser medium gas supply/exhaust device is activated to replace the laser medium gas in an optical resonator. The excitation of the laser medium gas and the replacement of the laser medium gas are repeated until exciting power dispersion≤dispersion upper limit. |
