摘要： A high power gas laser and, in particular, a high power continuous wave gas laser. The discharge chamber of the laser has a plurality of first electrodes. The electrodes of opposite polarity take the form of a coil. The first electrodes take the form of a plurality of metal pins protruding from the wall of the discharge chamber. Gas is introduced into the discharge chamber tangentially which circulates with a vortex type motion from the upstream instroduction point to the exit chamber where it is split and exits by a conical flow divider. A portion of the gas travels from the flow divider upstream due to the back pressure of the flow divider resulting in improved vortex flow in the discharge chamber and exits at the upstream end. The discharge chamber of the laser may assume a conical configuration.

摘要： A laser resonator system including an optical resonator whose side wall has an orifice through which gas may enter the resonator's interior, and may subsequently flow along the resonator's longitudinal axis. An elongated electrode (which preferably is an anode) is positioned at the orifice in electrical communication with the entering gas so that the projection of the electrode's tip on the plane of the orifice does not coincide with the center of the orifice. In a preferred embodiment, the electrode's longitudinal axis is aligned generally perpendicular to the plane of the orifice. In another preferred embodiment, two such electrode-orifice pairs are provided and are separated by a small distance along the resonator's axis. The orifice positions are preferably on opposite sides of the resonator, so that they are separated by an azimuthal angle substantially equal to 180.degree. with respect to the resonator tube's longitudinal axis. The relative position and orientation of each electrode-orifice pair results in an improved, flatter gas velocity profile downstream from the orifice.

摘要： An optically stable resonator producing a laser beam which by the use of a converging and of a diverging optical element is subdivided into an amplifier part with large beam diameter and small energy density and into a mode filter part with small beam cross section and correspondingly small Fresnel number all with a short structural length of the resonator. The advantage of the present invention resides in the high beam quality of the produced beam which contains predominantly only the fundamental mode, and in the small thermal load of the participating elements, especially of the decoupling window. The subdivision of the stable resonator according to this invention into an amplifier part and into a load filter part opens up to this resonator type power output ranges which were precluded heretofore by reason of a maximum permissive thermal load of the decoupling window.

摘要： In a gas laser device according to this invention, a gas inlet having an electrode protrudes within each of expanded portions protruding on the side, where the gas inlet is disposed, of the principal portion of the discharge tube. Gas medium ejected from the gas inlet in the principal portion of a discharge tube collides with the inner surface of the principal portion of a discharge tube, while forming a flame extending along the ejected gas medium from the electrode and is divided into two partial flows. One of them flows along the wall of the expanded portion; collides with the gas inlet; and is divided further into two partial flows. Therefore it does not collide with the gas medium within the gas inlet. Consequently the gas medium and the flame fluctuate hardly and are stabilized. In this way it is possible to stabilize the laser output.

摘要： An ion plasma electron gun for the generation of large area electron beams with uniform electron distribution. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid into a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid and the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and a uniform electron distribution which is substantially the same as the ion distribution of the ion beam impinging upon the cathode. Control of the generated electron beam is achieved by applying a control voltage between the wire and the grounded housing of the plasma chamber to control the density of positive ions bombarding the cathode.

摘要： In order to facilitate the initiation of plasma discharge inside a gaseous discharge tube, some form of pre-ionizing the gas is required. This invention describes a technique whereby a small but intense discharge region is created near the cathode of a d.c. discharge in order to generate the necessary electrons to initiate the formation of the main electrical discharge. It makes use of the high negative voltage that is applied on the discharge cathode with respect to the discharge anode. A third auxiliary pin electrode near the cathode is introduced into the discharge tube. It is connected on the outside to the anode through a resistor of a suitable value. In the presence of a high voltage across the main electrodes, corona discharge occurs near the auxiliary electrode. This leads to the formation of a small region of intense discharge between it and the cathode. The electron generated in this small discharge region would drift towards the anode under the high electric field between the main electrodes. The whole discharge volume would therefore be filled with energetic electrons and hence leads to the easy initiation of the main plasma discharge.
摘要翻译：为了便于在气体放电管内引发等离子体放电，需要某种形式的预电离气体。本发明描述了一种技术，其中在直流电场的阴极附近产生小而强烈的放电区域。放电以产生必要的电子以引发主放电的形成。它利用放电阴极相对于放电阳极施加的高负电压。阴极附近的第三辅助引脚电极引入放电管。它通过适当值的电阻器在外部连接到阳极。在主电极上存在高电压的情况下，在辅助电极附近发生电晕放电。这导致在其与阴极之间形成强烈放电的小区域。在该小电极中产生的电子将在主电极之间的高电场下向阳极漂移。因此，整个放电容积将被充满能量的电子填充，因此导致主等离子体放电的容易启动。
