Note that portions corresponding to those in FIG. 2 described above are designated by the same reference numerals. In the laser oscillation device of this embodiment, a dry gas outlet 6 is provided in a housing 1 via a valve 7, and a dry gas outlet 8 is provided on the opposite side via a valve 9. A dry gas supply device 10 for supplying dry gas to the dry gas population 6 is provided outside the housing 1 .

First, prior to starting the apparatus, the operation of the dry gas supply device 10 is started, and the valve 7.9 is opened to replace the air in the housing 1 with a dry gas, for example, dry air. After the time required for the replacement has elapsed, the operation of the cooling means 3 and the laser oscillator 2 is started. When the device is stopped, valve 7.9 is closed. In addition, by increasing the amount of drying gas introduced only during the initial drying gas replacement,
It is more efficient to use a valve 79 and a dry gas supply device 10 that can reduce the amount of gas introduced after replacement.
