摘要:
A stripline laser wherein the distance between a mirror and a stripline is minimized without modifying the characteristics of the laser is provided. The stripline laser prevents damaging of the mirror due to plasma discharge by providing at least two insulating strips arranged between oppositely polarized electrodes. Electrically conductive paths lie between the insulating strips. The insulating strips are arranged to guarantee a voltage division. The voltage division maintains the voltage of the electrically conductive path neighboring the mirror below a plasma-maintaining voltage.

In a gas laser having a capillary and a cathode that envelopes the capillary, a fastening of the cathode suitable for batch soldering is achieved in that the cathode is secured to an end piece having a mount for an optical element, and an end of the cathode facing away from the end piece is elastically supported against a housing wall with such a slight spring power that a weight of the unit formed of the cathode, end piece, and mount is adequate for overcoming the friction between the spring and the housing wall. Thus, the end piece with the attached cathode can slide into its final position during soldering solely on the basis of the force of gravity. The invention is particularly suited for helium-neon lasers that are manufactured in glass solder technology.
摘要:
An indicator device which has two sealed chambers which are formed by at least one carrier member interposed between a pair of glass plate members to provide a tandem arrangement in the direction of travel of light in the device, characterized by at least one of the chambers containing a liquid crystal layer and being provided with transparent conductive material on the walls thereof to form a liquid crystal cell. In one embodiment one liquid crystal cell is a rotation cell and the other is a DAP cell which cells can be activated to give multi-colored indications. In a second embodiment of the invention, one of the cells is a rotation cell and the other is a polarizing cell which enables giving a colored indication on a colored background or a white indication on a black background. In a third embodiment, both cells are rotational cells with a different angle of rotation and the carrier member consists of a birefringent material which enables indications of at least four different colors. In a fourth embodiment, each conductive layer of each cell is separated in two parts by a continuous interruption in the layer so by selectively applying voltage to different parts, at least four different symbols or shapes can be indicated. In a fifth embodiment, each of the cells is a rotational cell of approximately 45.degree. and the electrode pattern of each cell is a matrix of strips extending perpendicular to each other so that the time required for indicating an image on the device is reduced. In a sixth embodiment, the conductive layers of each cell are arranged as a segment electrode pattern with the segment being subdivided into partial segments with one partial segment being in one cell and the remaining partial segment in the second cell to enable determining errors in actuation of various segments during an indication. In a seventh embodiment, the liquid crystal cells are arranged in tandem one behind the other so that either by separately actuating the electrodes of each cell a sign or symbol can be produced without undesirable cross points or by sequentially activating the electrodes of each cell, a partial image can be produced in each cell to create a moving image on the device. In the eighth embodiment, one of the cells is provided with a reflective layer by either depositing from a silver-ammonium complex or by printing with a silver compound onto a surface of the chamber to provide a reflecting chamber which enables operation of the remaining cells in a reflective mode. In a final embodiment, an electrochemical luminescence layer is provided in one cell to provide an illuminating background for indications produced on the other cell.

A method of manufacturing gas lasers, such as He-Ne lasers or Ar lasers characterized by positioning the laser housing within a vacuum chamber, evacuating the vacuum chamber to evacuate the laser housing through a filling tube provided in the housing, baking the housing, then filling the vacuum chamber with the laser gas, which enters into the laser housing through the filling tube, subsequently forming a solder closure in the end of the sealing tube, the removing the laser housing from the vacuum chamber and subsequently permanently sealing the filling tube by pinching off the solder closure to form a cold-weld seal of the tube.

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.

A gas laser housing having a housing and a metal cap attached thereto, includes a mirror mount attached to the metal cap. The mirror mount is provided with an annular region of reduced diameter affixed to the metal cap to absorb mechanical stresses and thereby prevents stress crack corrosion at the circumference of the housing tube.
