摘要： A blower unit includes an elongate main mounting member, a stator, a fan subassembly, and a blower housing. The elongate main mounting member is the main structural member of the unit. The stator includes a stator core and stator windings, and the stator is secured to the main mounting member. The fan subassembly includes a rotor and a plurality of vanes. The rotor includes a substantially cylindrical iron ring and a magnetic portion having a substantially cylindrical shape. The magnetic portion is secured within the inner diameter of the iron ring and defines a rotor bore. The stator is located in the rotor bore and is concentric with respect to the rotor. The rotor is coupled to the plurality of vanes so that the vanes rotate with the rotor. The fan subassembly also includes bearing assemblies which are spring biased towards, and into rotatable engagement with, the elongate main mounting member. The fan subassembly further includes a shroud for partially enclosing the plurality of vanes.

摘要： An exemplary laser apparatus comprises an amplification medium which amplifies a coherent beam passing through the amplification medium, a pump which provides energy to the amplification medium, a tunnel having a first end proximate to the pump and a second end proximate to the amplification medium, wherein the energy provided by the pump passes through the tunnel en route to the amplification medium, and a moveable member for adjusting a spatial distribution of the energy provided to the amplification medium by the pump. The moveable member typically comprises a flat, reflecting strip or flap which redirects a portion of the energy of the pump beam to a peripheral region of the amplification medium. The angular and translational position of the flap is adjustable on line so that the pump distribution can be adjusted while the laser is running to reduce observed optical distortions caused by heating of the amplification medium.

摘要： An oven for heating a crystal for nonlinear frequency conversion of a laser beam. A grasping device resiliently grasps together the first and second sides of the crystal while allowing for generally unrestricted thermal expansion of the crystal. A heater element and a temperature sensor are each supported by the grasping device and are each in thermal contact with the crystal. A temperature controller is connected to the heater element and the temperature sensor.

摘要： A laser head includes a body having opposite ends, and a bore extending axially therethrough for defining a reflector. The body is a unitary member circumferentially around the reflector. The reflector includes a center cavity for coaxially receiving a laser rod, and a plurality of lateral cavities disposed parallel to and extending radially outwardly from the center cavity for receiving flashlamps for optically pumping the laser rod. Reflector and lamp endcaps are removably mounted to the body for mounting the lamps and rod, and allowing individual replacement thereof.
