摘要： A laser oscillator which can effectively remove scattered light by a simpler configuration. The laser oscillator comprises an output mirror and a rear mirror which are arranged facing each other and a discharge tube which is arranged between the output mirror and the rear mirror. The discharge tube has a first part which gets larger in inner diameter from a first end part in an axial direction facing the output mirror toward the rear mirror.

摘要： A gas laser has a capillary which is supported inside a jacket tube by a resilient arrangement, which includes a spring washer having radially extending fingers extending from an annular portion having an axial aperture which is received on a cylindrical portion of a flange ring of the arrangement. The flange ring is soldered to the capillary tube with a glass solder in a manner which prevents the spring washer from coming in contact with the glass solder to change the properties of the spring washer.

摘要： The capillary of the gas laser is fastened with respect to the housing tube in a particularly accurate and tension high free manner in that a support is provided in the housing tube which is not in direct contact with the capillary, but is connected to the capillary in a mechanically-rigid fashion by way of glass solder. The invention is particularly advantageous in helium-neon lasers and lasers having long capillaries.

摘要： The turn-on delay of a cold cathode gas tube, such as a gas laser, is significantly reduced by the inclusion of an electric field concentrator in a region of the tube between the tube anode and cathode. The concentrator can take the form of a projecting conductive member having a sharp corner, linear or curved knife edge, needle like points, or combinations of such geometries.

摘要： An integral mirror type laser system which produces miltiline emissions simultaneously and which is adapted for use in optical data processing systems. In particular, in a first embodiment, a unitary positive column laser comprises two sections, the first section comprising a positive column helium-cadmium laser, the second section comprising a positive column helium-neon laser, the first and second sections being coaxially aligned and having different inner diameters. Simultaneous excitation in the two different sections provides optimum excitation for red laser light, produced by the helium-neon section and blue laser light produced by the helium-neon-cadmium section. The present system also allows separate cadmium vapor pressure control by separately controlling the vaporization temperature of the cadmium and also allows confinement of the cadmium vapor whereby the vapor does not contaminate one of the optical windows which confines the active laser medium. By proper selection of the optical cavity parameters, simultaneous red and blue laser oscillations can be obtained for application in any optical data processing system that requires a red and blue laser radiation source. In a second embodiment, the helium-cadmium section is replaced by with a helium-selenium section whereby the tandem laser system is capable of producing multiline laser radiation in the red, blue and green colors.
摘要翻译： 一体化的镜面式激光系统，可以同时产生微粒排放，适用于光学数据处理系统。 特别地，在第一实施例中，单一正列激光器包括两个部分，第一部分包括正列氦镉激光器，第二部分包括正列氦氖激光器，第一和第二部分同轴对准， 具有不同的内径。 在两个不同部分的同时激发为由氦氖部分产生的红色激光和由氦氖镉部分产生的蓝色激光提供最佳激发。 本系统还允许通过分开地控制镉的蒸发温度来分开镉蒸汽压力控制，并且还允许限制镉蒸气，由此蒸汽不会污染限制活性激光介质的光学窗口之一。 通过适当选择光腔参数，可以获得同时的红色和蓝色激光振荡，用于需要红色和蓝色激光辐射源的任何光学数据处理系统。 在第二实施例中，氦 - 镉部分被氦硒部分代替，由此串联激光系统能够产生红色，蓝色和绿色的多行激光辐射。

摘要： In a coaxially constructed gas laser with a capillary fused at one end to the glass casing surrounding it and enclosed at its free end by a supporting spring the supporting spring contains a perforated disc of a material adapted thermally to the jacket glass and is framed by a shrunk-on jacket constriction. Such a mount is extraordinarily stable mechanically and thermally. In a preferred embodiment the supporting spring is a multipart spring: attached to the thermally adapted perforated disc are two other, smaller perforated discs consisting of a spring material of temperature constancy and containing the actual spring elements.

摘要： In a gas laser tube including a laser capillary tube having one fixed end secured to the envelope surrounding the capillary tube and one free end. A support structure for the free end comprising a discharge diverting tube extending from the envelope toward and overlapping the free end of the laser capillary tube and a coil spring interposed between the free end portion of the laser capillary tube and the inner wall of the discharge diverting tube. The free end portion of the capillary tube is supported resiliently by the coil spring and the capillary tube is kept straight without bending or vibrating while absorbing the elongation of the capillary tube caused by thermal expansion.

摘要： A laser gyroscope is disclosed wherein a polarization dispersive structure, disposed in the path of the laser beam, includes an anisotropic crystal as a half-wave retarder.
