摘要： 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. The second L shaped network includes a second inductor having a first end connected to the common connection between the second end of the first inductor and the first plate of the first capacitor and a second capacitor having a first plate connected to the second end of the second inductor and a second plate connected to ground. The common connection between the second end of the second inductor and the first plate of the second capacitor is connected through the shielded, hermetically sealed laser tube housing to the electrodes of the slab laser system. The two L-shaped networks may be implemented in a “single capacitor” configuration for lower power applications or in a “multi-capacitor” configuration for higher power applications.

摘要： The present invention provides a cylindrical slab type gas laser for generating an excellent laser beam having substantially Gaussian intensity distribution of the focussed output laser beam. For this end, a pair of cylindrical electrodes 11, 12 of different diameter are disposed vertically and concentrically. And laser medium is filled in the gap between the two cylindrical electrodes 11, 12 to define a cylindrical straight slab 1. Disposed at one end of the cylindrical top of the cylindrical straight slab 1 is a ring-shaped trick mirror M1 and also disposed at the center of the one end of the cylindrical straight slab 1 is an output mirror M2 to pass a part of the light and to reflect a part of the remaining light. On the other hand, disposed at the other end of the cylindrical straight slab 1 is a w-axicon mirror M3. The above construction eliminates the need for spacers between the two cylindrical electrodes 11, 12 which are required in a conventional gas laser.

摘要： A high output, compact laser having a multi-line spectral output and an internal mirror, integral resonator design is disclosed. The laser structure comprises a laser tube containing a resonant cavity, an output coupler and an active medium. A power supply and coolant assembly are coupled to the laser tube. The coolant assembly is a hybrid coolant scheme wherein one portion of the tube is cooled by circulating water coolant, while another portion or portions are cooled by circulating air. In one aspect, the laser tube includes a ceramic bore surrounded by a sheath sealed at a first end and a second end of the ceramic bore, and coolant is provided between the sheath and the bore. In a further aspect, forced air is directed over a reservoir portion of the tube. The reservoir portion may be manufactured from a metallic alloy comprised of nickel iron cobalt with copper cooling fins brazed to the reservoir to increase thermal cooling efficiency and isothermal distribution of heat.

摘要： A heat conducting structure in a discharge tube of an ion laser, that has high resistance to erosion due to sputtering comprises a discharge limiting member having an inner aperture, and a thin film of refractory ceramic coating areas near the inner aperture. The thin film of ceramic does not significantly retard heat flow out of the discharge into the heat conducting structure, but significantly increases resistance of the heat conduction structure to sputtering.

摘要： A disk, or heat web, is generally circularly shaped, and has a circumferential lip normal to the plane of the disk. A split ring, fabricated from a material having a low co-efficient of thermal expansion fits within the circumferential lip. A generally circularly shaped expansion member, made from a material having a relatively high coefficient of thermal expansion, fits within the split ring. A suitable brazing material is placed between the split ring and the circumferential lip of the disk. The heat produced by the brazing process expands the split ring and allows it to be brazed into place when the assembly is placed on the inside of the cylindrical member.
