摘要： In a miniature Q-switched, pulsed laser, having a two arm folded resonator, Q-switching is effected by rapidly and reciprocally tilting a resonator mirror of the laser about an axis perpendicular to the axis of the laser resonator. The angular excursion of the tilting and the frequency of the tilting are selected cooperative with dimensions of the resonator to maximize energy and symmetry of intensity distribution in Q-switched pulses delivered by the laser. Rapid reciprocal tilting of the mirror is accomplished using a piezoelectrically-driven, MEMS scanner operated in a resonant mode.

摘要： A longitudinal diode-laser array includes a plurality of diode-laser emitter groups. The emitter groups are mounted on corresponding electrical contacts electrically isolated from each other on a dielectric carrier. The emitter groups are cut from a conventionally formed diode-laser bar bonded to the carrier. The emitter-groups are connected together in electrical series via the electrically isolated electrical contacts. This provides that the diode-laser array can be operated at a lower current than would be required to operate the conventional diode-laser bar wherein the plurality of emitters must be connected in parallel.

摘要： A diode-laser bar package includes a diamond composite heat-sink on which is soft-solder bonded a copper-pad having an area much greater than that of the diode-laser bar. A constraining-block of a metal having a CTE matching that of the diode-laser bar is hard-solder bonded to the conductive pad. The constraining-block is configured such that the conductive pad in the region of the diode-laser bar has a CTE about equal to that of the constraining-block, and, accordingly, the diode-laser bar.

摘要： A laser printer arranged to print a pixellated image on laser sensitive tape includes a carriage on which are arranged two laser-beam sources delivering separately modulated laser-beams and optics for focusing the beams on the tape. The tape is mounted on a tape drive which drives the tape incrementally in one direction. The carriage is translated over the tape in a direction perpendicular to the tape-drive direction, while the modulated beams are focused. Two rows of the pixellated image are drawn across the tape in this manner. The tape is then incremented and a further two rows are drawn.

摘要： A balanced microdevice comprising a substrate, a movable structure overlying the substrate, an element and a lever assembly having a pivot and a lever coupled to and pivotable about the pivot. The lever has a first extremity coupled to the movable structure and an opposite second extremity coupled to the element. The movable structure causes the lever to pivot about the pivot so as to move the element in a direction of travel. The element is substantially mechanically balanced to inhibit undesirable movement of the element in the direction of travel in response to externally applied forces.

摘要： Micro-machined tools and component holders useful for the manufacture, assembly, and testing of precision micro-miniature parts are provided, particurlarly embodiments well adapted for precision micro-miniature systems incorporating optical and/or electronic components including lenses, optical fibers, and the like. Structure and method find particular applicability in the precision optical systems of the read, write, or read/write heads of optically assisted storage devices for digital computers. Removable tools are used to temporarily position components while the components are glued or otherwise fixed into place during assembly, and then completely removed for use with another head assembly. Break-away tools or holders typically include three major portions: an element holder, a handle, and a break-away neck portion connecting the holder with the handle. The element holder provides a mounting block for an optical, electrical, or mechanical element. Once the elements are attached to the mounting blocks, they are moved into position within the larger assembly via the handle, the mounting block is glued to the assembly and a small predictable force is applied to the handle to break the neck and separate the handle from the holder which is at that time attached to the assembly. Tools may be formed by photolithographically patterened and etching a substrate such as silicon to selectively carve the substrate. Structures formed from plated metal, either on a base material, or made entirely of metal are also provided by the invention. Several embodiments of process for forming the inventive structures are also provided.

摘要： A micromachined structure for handling fluids with an applied high voltage, i.e. for electrophoresis, includes a glass or other highly insulative substrate on which are formed very small diameter capillary channels of e.g. silicon nitride. Due to the absence of a silicon substrate, this structure is highly electrically insulative. The silicon nitride channels are formed by a micro-machining and etch process, so that they are initially defined in an etched sacrificial silicon wafer by conformal coating of etched features in the silicon wafer with a silicon nitride layer, which is then patterned to define the desired channels. The silicon wafer is bonded to the glass substrate and the bulk of the silicon wafer is sacrificially etched away, leaving the desired silicon nitride channels with supporting silicon mesas. The remaining silicon nitride "shell" is bonded to the glass substrate and substantially duplicates the etched features in the original silicon wafer. The capillary channels are of a material such as low stress silicon nitride and there is no electrical shorting path to the highly insulative glass substrate.

摘要： A precise fluid flow meter fabricated by micromachining techniques measures a wide range of fluid flow rates. Two serial portions of an enclosed channel have different cross-sectional areas, and therefore different flow velocities. The fluid carries the thermal pulse through the flow channel to two sensor elements spaced apart along the channel downstream from the heating element. The transit time of the thermal pulse between the two sensor elements measures the fluid flow velocity.
