果を有している。In the radiated noise shielding laser oscillator of the present invention, the entire circumference of the laser head is covered with a conductive material, and the divided parts of the conductive material are tightly connected to each other through a conductive packing. It has an effect of shielding radiation noise generated from each electric component included in the laser head.

の放射ノイズを遮蔽する。The cover 1 of the laser head is made of metal, and the inside surface of the oscillator is not subjected to any treatment such as painting to impair its conductivity. Also in the base 2 of the laser head, the same material as the cover 1 is made of metal, and the inner surface of the oscillator and the joint with the dustproof packing 3 are not subjected to any treatment such as painting to impair the conductivity. The laser head is covered with a closed conductive box when the above three members are assembled by making the dustproof packing 3 at the joint between the cover 1 and the base 2 conductive (conductive rubber or the like). Shields radiated noise from electrical components installed inside the laser head.
