Abstract

PURPOSE:To maintain stable discharging state of a gas laser device by forming each rod-shaped electrode in an outer wall conductive heat pipe, thereby providing cooling operation capability at the electrode itself. CONSTITUTION:A plurality of anodes 2, 2,... supported by an electrically insulating support plate 1 are all formed of outer wall conductive heat pipe, and are sequentially arranged at the prescribed interval to oppose to the surface of a cathode 3 at the ends and to direct toward the longitudinal direction of the cathode 3. The upper end of the anodes 2 are commonly connected through a stable resistor 4 to a power source 4. Trigger electrodes 6 are provided to lower the starting discharging voltage, and are normally used in plural number. When a discharge is started between the anodes 2 and the cathode 3, the ends of the anodes 2 are heated, but since the anodes 2 made of the heat pipes operate to transfer heat from high temperature unit to low temperature unit, thereby performing self-cooling operation to suppress the temperature of the anodes 2 to raise to excessively high temperature.

Description

【発明の詳細な説明】 本発明は、放電７部の動作安定化を図ったガスレーザ装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas laser device in which the operation of a discharge section is stabilized.

がスレーザ装置においては、その放電部の一方の電極が
多数個の棒状電極を列状に配設しな構成をもつが、従来
、この棒状電極の温度上昇のために放電が不安定になる
ことが多くあった。However, in a laser device, one electrode of the discharge section has a structure in which a large number of rod-shaped electrodes are arranged in a row, but conventionally, the discharge becomes unstable due to the temperature rise of this rod-shaped electrode. There were many.

本発明の目的は、上記棒状電極自身に冷却作用を持たせ
、もって安定な放電状態を維持させるようにしたがスレ
ーザ装置を提供することにある。An object of the present invention is to provide a laser device in which the rod-shaped electrode itself has a cooling effect, thereby maintaining a stable discharge state.

このため本発明では、上記各棒状電極を外壁導電性のヒ
ートパイプで形成するようにしている。For this reason, in the present invention, each of the rod-shaped electrodes is formed of a heat pipe having an electrically conductive outer wall.

以下、図示する実施例を参照しながら本発明の詳細な説
明する。Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

共通接続しである。In the drawing, a plurality of anodes 2, 2, ... supported by an electrically insulating support plate 1 are all formed with conductive heat/dive on the outer wall, and their tips are connected to the cathode 3. They are arranged in sequence at predetermined intervals in the longitudinal direction of the cathode 3 so as to face each other. The upper ends of each of the anodes 2 are commonly connected to a power source 5 via a stabilizing resistor 4.

なお同図に示すトリガ電極６は、放電開始電圧を下げる
た応に設けたものであり、通常において被数本使用され
る。Note that the trigger electrode 6 shown in the figure is provided to lower the discharge starting voltage, and normally several pieces are used.

上記各陽極２と陰極３間で放電が開始されると、該陽極
２の先端部が発熱するが、ヒート／ぐイブからなるこの
陽極２は高温部から低温部へと熱全輸送する作用をなす
ので自己冷却し、したがうて該陽極２の温度が過度に上
昇することは抑制される。When a discharge is started between each of the anodes 2 and cathodes 3, the tip of the anode 2 generates heat, but the anode 2, which is composed of a heat tube, has the effect of transporting all of the heat from the high-temperature part to the low-temperature part. Therefore, the anode 2 is self-cooled, and therefore the temperature of the anode 2 is prevented from rising excessively.

なお上記実施例では陽極２の上端部ｔ−側方に折曲げで
あるが、これは空中への放熱面積を増すためであり、か
（することによって陽極２の自己冷却作用をより向上さ
せることができる。In the above embodiment, the upper end of the anode 2 is bent to the t-side, but this is to increase the area of heat radiation into the air. Can be done.

本発明は、上記とは逆に陰極を複数個の棒状電極で構成
したがスレーザ装置にも当然適用することができる。In the present invention, the cathode is formed of a plurality of rod-shaped electrodes, contrary to the above, but it can naturally be applied to a laser device as well.

上記するように本発明に係るがスレーザ装置は、放電部
