Beschreibung
Zusammenfassung:	A gas laser oscillation device of the present invention including a blower unit having a rotating part that rotates, which includes an impeller, a rotating shaft, a motor rotor and a portion of bearings that are brought into contact with the rotating shaft, and a non-rotating part that does not rotate, which includes a motor stator, a casing and a portion of the bearings that are brought into contact with the casing. Two bearings are disposed between the rotating part and the non-rotating part. A grease supply mechanism that supplies grease to each of the two bearings is provided. A control unit drives the blower unit at a rotation rate lower than a rotation rate when a laser is output, after grease is supplied from the grease supply mechanism to the two bearings.
