Patent number: 11545807Abstract: A compact laser system with a folded annular resonator cavity defined by spherical mirrors (17, 18), enabling the generation of a multipass beam path between the mirrors, each beam pass inclined at a small angle to the axis between the mirrors to form a zig-zag path (28, 29) therebetween. A long optical path is achieved within a short physical structure. The optical resonator cavity is confined in the gap between two cylindrical coaxial electrodes (13, 14) receiving RF power to excite the lasing gas. Apertures (23) are provided in the main cavity mirrors (17, 18), with a high reflectivity end mirror (24) behind one aperture at one end and a partially reflective output coupler (25) at the other end. A channeled ceramic cylindrical element (15, 20) within the annular shaped gap between the two cylindrical electrodes confines the lasing gas to the channels (16).Type: GrantFiled: January 29, 2019Date of Patent: January 3, 2023Assignee: IDEA MACHINE DEVELOPMENT DESIGN AND PRODUCTION LTD.Inventors: Shlomo Turgeman, Mordechai Brestel, Eitan Sheffer, Michael Remes, Ben Zion Lavi

Patent number: 7829019Abstract: A casing for use as a test kit that employs crushable ampoules prefilled with chemical or biological reagents, comprising a molded casing having a distinct reaction chamber, and at least one distinct cell adapted for receiving a crushable ampoule. The cell has a flexible pressing area at its outer wall for pressing and crushing the ampoule. An opening exists between the chamber and the cell that is either narrow enough, or provided with filtering means so as to allow passage of the reagent while preventing passage of glass shards from the cell to the chamber. The casing further comprises an inlet leading from the exterior of the casing into the inner space of the reaction chamber and a sampling probe, for enabling obtaining samples of material and delivery of said material through the inlet to the reaction chamber.Type: GrantFiled: May 3, 2004Date of Patent: November 9, 2010Assignee: Identa Ltd.Inventors: Baruch Glattstein, Shmuel Huss, Mordechai Brestel
