Patent number: 8201954Abstract: A mirror assembly for a carbon dioxide (CO2) slab laser resonator includes a center section having a rectangular cross-section and a pair of thermal balancing bars. A concave reflecting surface formed on a front edge of a center section. The side-bars are attached to either side of the center section and extend forward of the reflective surface. Dimensions of the center section and side bars are selected to position the thermal neutral plane of the assembly close to the reflective surface. This minimizes changes the radius of curvature of the reflective surface due to heating by circulating radiation in the resonator.Type: GrantFiled: May 12, 2009Date of Patent: June 19, 2012Assignee: Coherent, Inc.Inventors: Adrian Papanide, Leon A.

Patent number: 7965757Abstract: A laser mirror assembly is disclosed with improved pointing stability. An elongated mirror includes a concave reflecting portion. A pair of elongated planar portions extend parallel to the concave reflecting portion on either side thereof. The planar portions are stepped down from the reflecting portion. The mirror is formed from copper. A pair of stainless steel strips are connected to planar portions. The bimetallic effect between the copper mirror and the stainless steel strips operates to counteract the warping of the mirror due to differential heating effects which arise during operation. In an alternate embodiment, a pair of aluminum strips are mounted on the rear surface of the mirror.Type: GrantFiled: December 31, 2009Date of Patent: June 21, 2011Assignee: Coherent, Inc.Inventors: Leon A.

Patent number: 7756182Abstract: The laser tube housing of a CO2 slab laser is provided with a cooling system in which coolant fluid tubes are inserted into hollowed out portions formed in the longitudinal sidewalls of the laser tube housing; mounting the coolant fluid tubes in this way provides for enhanced cooling and increased stiffness of the laser tube housing. Also, a cooling system is provided for the laser's electrode assembly that relies on a manifold system that is mounted on a longitudinal sidewall of the laser tube housing to route coolant fluid through the sidewall to the electrode assembly; sidewall flow of the coolant fluid enables the end flanges of the laser tube housing to be remove without disturbing either the electrodes or the optical resonator of the laser.Type: GrantFiled: March 26, 2008Date of Patent: July 13, 2010Assignee: Coherent, Inc.Inventors: Leon A.

Patent number: 7540779Abstract: A RF shielded, series inductor, high power impedance matching network interconnector is provided for connecting an RF power supply to electrodes contained in the shielded, hermetically sealed laser tube housing of a slab laser system. The impedance matching interconnector comprises a short length of co-axial conductor and an impedance matching network that includes two L shaped networks. The inner conductor of the co-axial conductor is connected between the power supply output and the impedance matching network. The outer conductor of the co-axial conductor is grounded. The co-axial conductor has an impedance characteristic to match the power supply output impedance. The first L-shaped network includes a first inductor having a first end connected to the inner conductor of the co-axial conductor and a first capacitor connected to the second end of the first inductor and a second plate connected to ground.Type: GrantFiled: March 19, 2008Date of Patent: June 2, 2009Assignee: Coherent, Inc.Inventors: Adrian Papanide, Frederick W.

Publication number: 20070012367Abstract: A flow setting assembly is provided to permit field adjustment of an electronically actuated flow control valve, particularly a pressure independent characterized control valve (PICCV). In a preferred form, flow can be field adjusted by using a hex tool. Therefore, the maximum flow can be increased or decreased within the valve's adjustable flow range. As with all high close-off valves that employ a ball in their design, the ball passes well into the seat when rotated to the actuator's zero-degree position. Therefore, there is an amount of travel within the first degrees of ball rotation that passes back over this seat. The flow setting assembly eliminates this excess rotation (12°) resulting in a closed position that is offset to improve control resolution and system accuracy. This offset continues to allow the high close-off rating of 200 PSI. MFT actuators electronically adjust to and maintain the 2-10 Volt control signal at the reduced angle, as well as the 100 second running time and feedback signal.Type: ApplicationFiled: May 8, 2006Publication date: January 18, 2007Inventors: Beat Hotz, Adrian Papanide
