Patent number: 5982803Abstract: A pair of elongated, parallel electrodes (91,92) are insulatively mounted within a tubular housing (111) filled with a laser gas mixture between an arrangement of reflective optical elements (120,150) sealingly mounted at each end of the housing. The electrodes form a rectangular gas discharge area (40) the minimum spacing (a) between which is the diameter of the fundamental free-space mode of the stable, laser resonator (17) formed in the gap when the electrodes are rf excited (13). A multi-pass optical configuration (30,50) uses the full width (b) of the active medium to produce a high power, compact laser (10,200). Deformable support rings (97) are compressed to push the electrodes apart against small cylindrical spacers (99) abutting the inner walls of the housing to maintain the electrodes' spatial relationship. The rf feeds (103) sealingly (112) connected to the electrodes through the housing without disturbing the uniform distribution of forces on the electrodes.Type: GrantFiled: April 23, 1997Date of Patent: November 9, 1999Assignee: Universal Laser Systems, Inc.Inventors: Yefim P. Sukhman, Mikhail E. Ryskin, Christian Julian Risser

Patent number: 5901167Abstract: A gas laser design (10) includes, an elongated sealed tube (21) filled with a gas, a power supply for exciting the gas, an optical resonator (24,25) for producing directional optical energy, and a fan/electronics package assembly (50), all of which are surrounded and enclosed by an external housing (30,70,90) forming a passageway in the space between the tube and the housing for providing cooling air therethrough. The passageway is divided into two physically separated cooling air paths by a horizontal surface (21a or 41). The lower space is a dual L-shaped path defining the first cooling air path downwardly at the inlet end of the tube in the vertical air channels (31,32) formed by the contoured shape of the tube and rearwardly (33) through the spaces (27,29) between the horizontal fins (26,28) of the tube to an outlet (101) at the rear of the tube.Type: GrantFiled: April 30, 1997Date of Patent: May 4, 1999Assignee: Universal Laser Systems, Inc.Inventors: Yefim P. Sukhman, Christian Julian Risser, Mikhail E. Ryskin

Patent number: 5881087Abstract: An extruded aluminum gas laser tube assembly (10) has a pair of extruded, elongated, electrically insulated, aluminum electrodes (23,24) adapted to couple to an external RF supply and supported in the laser tube in predetermined spaced-apart relationship relative to each other and to the laser tube (11). The electrode supporting structure is eight pairs of matching, longitudinal, machined grooves (12,21), four pairs at each end of the tube (11) and electrodes (23,24) in each of which pairs is received a cylindrical, insulated, anodized aluminum spacer pin (22) which slidably supports the electrodes in the tube and allows longitudinal expansion of the electrodes relative to the tube substantially without bending.Type: GrantFiled: April 30, 1997Date of Patent: March 9, 1999Assignee: Universal Laser Systems, Inc.Inventors: Yefim P. Sukhman, Christian Julian Risser, Mikhail E. Ryskin
