摘要： A rotor magnet driven optical shutter assembly with a permanent magnet rotor directly connected to and driving the rotation of an optical shutter blade, to alternately block or allow transmission of light through the shutter aperture. The rotor is cylindrical with optional center hole, is magnetized across its diameter, and rotates around a pivot bearing coaxial with its center axis. A stator is arranged around the rotor and is shaped so that, as the rotor rotates over its range of travel, the flux. through the electromagnet drive coil core varies in magnitude and direction. A drive current through the electromagnet drive coil thus induces a torque to the rotor, to open or close the shutter blade. By driving the electromagnet drive coil with a controlled current waveform, the shutter aperture may be opened or closed (either quickly or slowly), held open/closed, or moved to any intermediate position, as desired.

摘要： An intracavity frequency-converted laser having an intracavity reflector situated to reflect converted radiation at a nonzero angle with respect to the optical axis. The laser includes an optical cavity (40) that defines an optical axis, a gain medium (46) for providing a fundamental laser emission, a pump source (60) for pumping the gain medium, and a nonlinear material (62) for frequency converting the fundamental laser emission to provide first and second converted beams that propagate in opposite directions within the optical cavity. An angled reflector (70) that reflects optical radiation at the converted wavelength, but is transmissive at the fundamental wavelength is situated within the optical cavity to reflect one of the converted beams along a path angled with respect to the optical axis. Reflecting the converted radiation before it propagates through the gain medium avoids absorption losses. Furthermore, interference between the reflected beam and other converted beam is avoided due to the angle of reflection.

摘要： A honeycomb tabletop (11), has a honeycomb core (21) positioned between a top (13) and bottom (15) structural layer. A number of cups (25) are positioned between the bottom layer (15) and the top layer (13), and at least some of the number of cups (25) are sized and shaped to cooperate with the lower face (59) of the top layer (13) to form a cavity surrounding at least two of the plurality of holes (19) in the top layer (13) so that contaminants will be unable to pass through the surrounded holes (19) into the honeycomb core (21). These cups (25) form a sealing engagement with the lower face (59) of the top layer (13) to facilitate rapid and thorough cleaning of contaminants from the cups (25).

摘要： A second harmonic generator including a semiconductor laser as a pumping light source, a solid laser crystal excited by the pumping light source and a resonator having a control element for controlling the wavelength of a first oscillation wave, the fundamental wave, generated from the solid laser crystal and a non-linear optical crystal for converting the first oscillation wave to the second harmonic which is a second oscillation wave. A first laser mirror, the solid laser crystal, the wavelength control element, the non-linear optical crystal and a second laser mirror are disposed in this order from the incidence side of the pumping light, as the constituent components of the resonator.

摘要： An optical fiber coupling assembly for substantially preserving polarization of transmitted optical radiation, including at least one multimode optical fiber (100) situated in a housing (105) that includes means for distributing pressure on the optical fiber and reducing stress on the multimode optical fiber. In one embodiment, the housing has a first (110) and a second side (120), and includes a channel (430) having a first end opening on the first side and a second end within the housing. A cavity (420) connected to the second end of the channel is formed within the housing. An aperture (410) formed in the housing connects the cavity to the second side. The channel, cavity, and aperture together provide a passageway for the optical fibers from the first side to the second side of the housing. In the preferred embodiment, the aperture bundles a plurality of fibers together in an approximately circular cross section. A laser such as a laser diode or laser diode array (500) provides substantially polarized optical radiation that is coupled into a first end of the optical fibers. The optical radiation transmitted through the housing is outputted from the second side having substantially preserved polarization from the bundled second ends to provide a collective output beam having a substantially single polarization. The collective output beam is useful for pumping a solid state laser (510). The polarization preservation between the first and second ends may be greater than 70 %, and in some embodiments greater than 90 %.
