Description
【０００１】[0001]
本考案はレーザー光路切換器に関する。 The present invention relates to a laser optical path switching device.
【０００２】[0002]
従来は、レーザー光路切換器は、ミラーホルダー、回転軸、固定用軸及び軸受 け用ベアリング玉から構成されていた。その使用方法は、固定用軸を持って回転 させ、軸をベアリング玉の上に乗せて固定する方法であった。ミラーの切換によ る１０ｍ先でのスポット光のばらつきは１０ｍｍ程度もあった。これでは、実験 上問題があり、これを０．１ｍｍ以下のスポット光の位置ばらつきにする必要に 迫られていた。 Conventionally, the laser optical path switching device was composed of a mirror holder, a rotary shaft, a fixed shaft, and a bearing ball for bearings. The method of use was to rotate by holding the fixing shaft, and place the shaft on the bearing balls to fix it. The variation of the spot light 10 m ahead due to the switching of the mirror was about 10 mm. In this case, there was a problem in the experiment, and it was necessary to reduce the spot light position variation of 0.1 mm or less.
【０００３】 上記のように、ミラーを何回も切換えた時、１０ｍ以上の長距離放射されたレ ーザーは、従来のレーザー光路切換器では、１０ｍ先の当たる場所が変わり、実 験に使用できなかった。そのばらつき範囲は１０ｍｍ程度にもなった。As described above, when the mirror is switched many times, a laser emitted for a long distance of 10 m or more can be used in an experiment because the conventional laser optical path switcher changes the contact point 10 m ahead. There wasn't. The range of variation was about 10 mm.
【０００４】[0004]
本考案の目的は、細かいレーザー光、約３ｍｍ径のレーザー光を０．１ｍｍ以 下のばらつきで照射できることを目的としたレーザー光路切換器を提供すること にある。 An object of the present invention is to provide a laser optical path switching device which is capable of irradiating a fine laser beam or a laser beam having a diameter of about 3 mm with a variation of 0.1 mm or less.
【０００５】[0005]
本願考案者は、この目的達成のため鋭意研究の結果、本考案のミラーホルダー とそれを回転する軸及び軸受け、ミラーホルダーに取り付けられた磁石、ミラー 固定位置に取り付けられた鉄板のストッパーから構成されたレーザー光路切換器 を考案するに到った。 The inventor of the present invention, as a result of diligent research to achieve this object, is composed of the mirror holder of the present invention, a shaft and a bearing for rotating the mirror holder, a magnet attached to the mirror holder, and an iron plate stopper attached to the mirror fixing position. We also came up with the idea of a laser optical path switching device.
【０００６】 従来、ミラーホルダーの回転は自由で、それを一定場所に止めるだけの考え方 はあったが、本考案においては、その止め方（固定方法）に工夫を施した。すな わち、ミラーホルダーの側面に薄い磁石を接着し、その他には、ミラーホルダー 固定位置に磁石の吸着面にマッチした鉄板を固定した。使用方法は、ミラーホル ダーの持ち手を取って回転させ、固定位置の鉄板まで動かし吸着させ固定した。 その結果、ミラーホルダー内のミラーからのレーザー反射光は１０ｍ先で、繰り 返しミラーホルダーを回転しても、全く同じ位置に照射された。Conventionally, there has been an idea that the mirror holder can be freely rotated and stopped at a fixed position, but in the present invention, a method of fixing (fixing method) is devised. That is, a thin magnet was adhered to the side of the mirror holder, and an iron plate that matched the attracting surface of the magnet was fixed at the mirror holder fixing position. To use the mirror holder, take the handle and rotate it, move it to the iron plate at the fixed position, adsorb and fix it. As a result, the laser reflected light from the mirror in the mirror holder was 10 m ahead, and even when the mirror holder was repeatedly rotated, it was irradiated to the same position.
【０００７】 ＪＦＴ−２Ｍトカマク用ＴＶＴＳの実験では、レーザー装置から１０ｍ以上離 れて取り付けられたビームダンプの孔（直径約１０ｍｍφ）に入射して、約１０ 月間良い実験結果が得られた。In the experiment of TVTS for JFT-2M tokamak, it was incident on a beam dump hole (diameter of about 10 mmφ) installed at a distance of 10 m or more from the laser device, and good experimental results were obtained for about 10 months.
【０００８】 本考案のレーザー光路切換器を図面について説明する。 図１において、レーザー光Ａを入射する場合は、持ち手１をＸ方向に回転させ る。必要ならば、鉄板Ｌに吸着させ固定する。 レーザー光Ｂを入射する場合は、持ち手１をＹ方向に回転させ、鉄板Ｍに吸着 させ固定する。 レーザー光Ａ及びＢを入射する場合は、上記のレーザー光Ｂの場合と同じであ るが、ミラーホルダー２に取り付けたミラー３をハーフミラー等にしてミラーに 工夫を行う。A laser optical path switching device of the present invention will be described with reference to the drawings. In FIG. 1, when the laser light A is incident, the handle 1 is rotated in the X direction. If necessary, it is adsorbed and fixed on the iron plate L. When the laser beam B is incident, the handle 1 is rotated in the Y direction and is adsorbed and fixed to the iron plate M. When the laser beams A and B are incident, they are the same as in the case of the laser beam B described above, but the mirror 3 attached to the mirror holder 2 is changed to a half mirror or the like so that the mirror is devised.
【０００９】[0009]
異なった２本のレーザー光を、本考案のミラーホルダーの操作により、遠く離 れた全く同一の場所に入射することが可能となり、長距離レーザー放射時の放射 方向の再現性を向上させることができる。 By operating the mirror holder of the present invention, it is possible to make two different laser beams incident on the same place, which is far away, and improve the reproducibility of the emission direction during long-distance laser emission. it can.
