護ガラス管の固定構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a housing for a solid-state laser oscillator used in a solid-state laser oscillator that is operated by pumping solid rod excitation light, and in particular, This invention relates to a fixing structure for a protective glass tube for a lamp.

により、レーザ発振を実現することが出来る。BACKGROUND ART Conventionally, a housing for a solid-state laser oscillator is composed of a reflector for condensing excitation light emitted from an excitation lamp onto a rod-shaped solid rod, and an envelope for cooling the reflector. Typically, most of the light emitted from the excitation source by providing electrical input is reflected by a reflector and focused onto the h1 solid rod. Laser oscillation can be achieved by placing a pair of resonator mirrors on both sides of a solid rod pumped by excitation light.

の側板に取り付ける構造となっていた。Usually, the solid rod of the solid state laser oscillator housing, the excitation lamp, and the reflector must be provided with cooling means for heat dissipation of the electrical input. At this time, in order to increase cooling efficiency and obtain stable laser output, it is common to cool the excitation lamp after cooling the solid iron and reflector.In order to increase cooling efficiency and oscillation efficiency, the excitation lamp is cooled using a protective glass tube. It was designed to be attached directly to a pair of side plates together with a protective glass tube for the fixed rod.

。In the conventional solid-state laser oscillator housing described above, the protective glass tube for the excitation lamp and the protective glass tube for the solid rod are fixed by a common side plate. If the lamp protective glass tube is damaged, the entire solid-state laser oscillator housing must be disassembled, and alignment adjustment must be performed after reassembly.

護ガラ７、管を交換出来るという相違点を有する。In contrast to the above-mentioned conventional solid-state laser oscillator housing in which the excitation lamp protective glass tube and the solid rod protective glass tube are integrated, the present invention provides a stopper screw and fixing parts in addition to the excitation lamp protective glass tube. The difference is that by providing the protective glass tube for the excitation lamp, the protective glass tube for the excitation lamp can be replaced independently of the protective glass tube for the solid rod.

A protective glass tube 4 for the rod is fixed above the rod. The fixing part 7 is first lightly inserted into the left side plate 2 of the reflector. The excitation lamp protective glass tube 3 is inserted from the right side plate 1 of the reflector, and after the fixed part 7 of the left side plate 2 of the reflector is inserted, the excitation lamp protective glass tube 3 and the fixed part 7 are brought into close contact. Once the position of the excitation lamp protective glass tube is determined, the excitation lamp protective glass tube 3 is fixed with a stopper screw 5.
