  • Patent number: 4872179
    Abstract: A laser device includes a multipass resonator which has, in the beam path between two resonator end mirrors, at least two opposite beam folding mirrors with confronting mirror surfaces. At least one of the beam folding mirrors is limited in its width and at least one has a beam discharge area. To produce a low-order laser mode, preferably a 00 mode, the mirror surface of at least one beam folding mirror has its reflectivity dimishished in the region outside of the desired modes of radiation.

  • Patent number: 4752937
    Abstract: A gas laser has a coolable inner electrode for connection to a radio-frequency power source and a coolable outer electrode that is coaxial with and radially spaced from the inner electrode with an excitation space containing the gas to be excited in the radial space between the inner and outer electrodes. With a view to improving a laser of this type in such a way that excitation at higher power with retention of homogeneous discharge is possible, that gas decomposition is slower, and that any desired liquid coolant can be used regardless of the electrical conditions, the excitation space is radially bounded by two, tubular dielectric bodies which are coaxial with and radially spaced from each other.

  • Patent number: 4744091
    Abstract: A gas laser has (1) a reflecting body with a reflecting surface, (2) excitation space structure cooperative with the reflecting body for defining an excitation space which is open opposite the reflecting surface of the reflecting body, (3) devices for lasingly exciting a gas in the excitation space and (4) a mirror assembly. The mirror assembly has a mirror having a reflecting surface facing the opening in the excitation space. A radial flange is about the mirror with the reflecting surface of the mirror on one axial side of the radial flange. At least one spacer and, preferably three, circumferentially-spaced bars project from the excitation space structure and engage the radial flange substantially axially for supporting it at least one of axially slidably and tiltably. Bellows sealingly connect the one axial side of the radial flange to the opening of the excitation space structure and its other axial side to a backplate immovably connected to the spacer bar on the other axial side of the radial flange.

  • Patent number: 4204117
    Abstract: A sample analyzer includes a microscope for alternatively focusing an electromagnetic radiation on the sample to cause ion emission therefrom and visually observing the sample; a mass spectrometer for the mass analysis of the emitted ions; an illuminating device for lighting the sample for the microscopic visual observation thereof; an ion optical system for directing the emitted ions into the mass spectrometer; and a displaceably supported carrier carrying the ion optical system and at least one part of the illuminating device. The carrier has a first position in which the ion optical system is in an operating position in alignment with the sample and a second position in which the illuminating device is in an operating position in alignment with the sample. There is further provided an actuator for selectively moving the carrier into its positions in a direction generally perpendicular to the axis of the ion optical system.
