    摘要: A method for generating polarized laser output radiation utilizes a laser resonator whose active medium exhibits thermally induced birefringence. The radiation fields oscillating in the laser resonator are not subjected to polarization selection, and only the radiation field exhibiting the desired polarization state (p) is partially output. Only a prescribed polarization of the radiation fields of the laser radiation which can oscillate in the resonator can be partially output from the resonator with a prescribed output level and all differently polarized radiation fields remain in the resonator in a completely reflecting fashion.

    摘要: The invention relates to a vacuum grip system (10) for gripping at least one object (11a). The vacuum grip system (10) has a base unit (18) and at least two suction units (19, 20) affixed thereto, disposed at right angles to one another, and each having at least one suction gripper (21, 22). At least one of the suction units (19, 20) grasps the object or objects (11a) to be gripped from above, and at least one of the suction units (19,20) grasps the object or objects (11a) from one side. In order to provide The vacuum grip system (10) having maximum flexibility, it is proposed to affix the suction units (19, 20) to the base unit (18) such that, in order to grip the object (11a), the distance between the upper suction unit (19) and the lateral suction unit (20) may be varied. It is further proposed that the vacuum grip system (10) have a mechanical undergripper (25) upon which the gripped object (11a) may be laid.

    摘要: A surface-modified material and its associated method have been developed for surface modification of high temperature resistance alloys, such as FeCrAl alloys, in order to increase their oxidation resistance. The surface of the alloy is modified by treating it with a fluid, such as water-based colloidal silica dispersion. By this surface modification, the useful life of thin parts, such as wire and foil, has been significantly increased.

    摘要: The instant invention relates to a laser system for optical free space communications, in particular the generation of amplified laser light under conditions in outer space. In the process, an optical beam (72) to be amplified is conducted via a polarizing beam splitter (71) to a Faraday rotator (70) and brought from there to a neodymium crystal (68). By means of reflection, appropriate diffraction and passage through a quarter-wave plate (67), a multiple passage through the neodymium crystal (68) is forced and amplification is achieved by this.
