摘要： A chuck for a laser cutting/engraving rotary fixture comprises a chuck plate having a chuck plate axis of rotation and at least two mount brackets spaced symmetrically radially with respect to one another about the chuck plate axis of rotation. Each mount bracket comprises an inclined contact surface and each mount bracket is rotatably attached to the chuck plate about the mount bracket axis of rotation. The inclined contact surface can be selectively rotated between a first position with the inclined contact surface inclined toward the mount plate axis of rotation and a second position with the inclined contact surface inclined away from the mount plate axis of rotation. An effectively concave contact surface is defined with each of the inclined contact surfaces in the first position. An effectively convex contact surface is defined with each of the mount brackets in the second position for engaging an inner diameter of a work piece.

摘要： An engraving laser assembly comprises a tubular rail defining a plenum in an interior of the rail. A carriage is operatively associated with to the tubular rail for axial movement along the rail. A focusing optic is mounted to the carriage for focusing a laser beam to a focal point on an engraving plane operatively with the carriage. A gas inlet is operatively associated with the tubular rail and the inlet is configured for attachment to a source of pressurized gas to provide pressurized gas to the plenum. A plurality of holes are provided in the tubular rail in fluid communication with the plenum. The holes are configured so that, with a source of pressurized gas attached to the gas inlet, a stream of pressurized gas is directed from each hole toward the engraving plane.

摘要： An RF-excited waveguide laser module comprises a first electrode having a first elongate surface defining in part a waveguide laser channel extending along an optical axis, the first elongate surface having a substantially linear cross-section normal to the optical axis. A second electrode has a second elongate surface defining in part the waveguide laser channel extending along the optical axis. The second elongate surface has a non-linear cross-section normal to the optical axis. A dielectric insert may be provided between the electrodes defining in part the waveguide laser channel. A lengthwise gap may extend essentially an entire length of the waveguide laser channel between one of the first and second electrodes and the dielectric insert. The gap provides fluid communication between the waveguide laser channel and a volume outside the waveguide laser channel.
