摘要： 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 (40) are connected to planar portions (26). The bimetallic effect between the copper mirror and the stainless steel strips (40) 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.

摘要： 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.

The impedance matching interconhector comprises a short length of co-axial conductor (122) and an impedance matching network (118) that includes two L shaped networks The inner conductor of the co-axial conductor (122) is connected between the power supply output (102) and the impedance matching network (118). The-outer conductor of the co-axial conductor (122) is grounded. The co-axial conductor (122) has an impedance characteristic to match the power supply output impedance (Zp). The first L-shaped network includes a first inductor (L1) having a first end connected to the inner conductor of the co-axial conductor (122) and a first capacitor (C1) connected to the second end of the first inductor (L1) and a second plate connected to ground.

The common connection between the second end of the second inductor (22) and the first plate of the second capacitor (C2) is connected through the shielded, hermetically sealed laser tube housing (106) 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 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. Also, a bracket assembly is provided for attaching the laser's electrode assembly to a longitudinal sidewall of the laser tube housing; the bracket assembly includes two brackets each of which is attached to a respective end of the electrode assembly and each of which is also attached to a longitudinal sidewall of the laser tube housing in proximity to a respective longitudinal end of the laser tube housing.

摘要： A compact CO 2 slab-laser is contained in a fluid cooled housing having three compartments. One compartment houses discharge electrodes and a laser resonator. Another compartment houses a radio-frequency power supply (RFPS) assembled on a fluid-cooled chill plate and an impedance-matching network. The remaining compartment houses beam- conditioning optics including a spatial filter. The housing and RFPS chill-plate are on a common coolant- fluid circuit having a single input and a single output. The spatial filter is optionally fluid-coolable on the common coolant fluid circuit.
