摘要： In a CO2 laser a pre-ionizer is assembled in a flange configured to be attached to a laser-gas enclosure of the laser over an aperture in a wall of the enclosure. An aperture in the base of the flange is aligned over the aperture in the enclosure wall. The aperture in the pre-ionizer flange is covered by a ceramic membrane. A disc electrode is in contact with the ceramic membrane on a side of the membrane outside of the laser-gas enclosure. An RF potential applied to the disc electrode creates a corona discharge on the side of the ceramic membrane inside the enclosure. The corona discharge ionizes laser gas in the enclosure before RF power is applied to electrodes of the slab laser.

摘要： An RF excited gas discharge laser is disclosed including a housing holding the lasing gas. An electrode assembly is mounted within the housing. The electrode assembly includes a pair of elongated planar electrodes mounted in face to face relationship with a narrow gap therebetween. A pair of planar dielectric plates are positioned along the side edges of the gap to seal the discharge region. The plates extend part of the way into the gap from both sides edges of the electrodes. The inner surfaces of the electrodes are provided with an opposed trench in the region surrounding the inner edges of the plates. In this way, the exposure of the inner edges of the plates to the discharge is minimized improving performance.

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： Through the use of a relatively inexpensive third mirror on a novel folded hybrid unstable resonator configuration, the optimum output coupling for a given laser design can be explored quickly and easily with a minimum of intracavity mirror alignment. No changes in either the radii of curvature of the three cavity optics or their spacing are required for this exploration. In addition to providing techniques for purposefully and systematically introducing mirror edge effects or avoiding edges effects altogether, the invention provides that output beams of different width can be advantageously explored in a relatively simple and straightforward manner. The invention provides that higher geometric magnification cavity designs may be made compatible with low diffraction output coupling in a configuration that uses only three totally reflecting optics.

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.
