    摘要： Micromachined organic crystals are used in electro-optic modulators to provide high speed modulation capability. Machined modulator blocks of organic crystal material, such as dimethylamino n-methylstilbazolium tosylate (DAST), have smooth surfaces adapted to couple light between the organic crystal and a medium adjoining the crystal in the electro-optic modulator. Electrodes are disposed with respect to the modulator block such that an electric field is generated along a selected axis corresponding to the polar axis of the organic crystal. A method of machining the soft organic crystal adapted for use as a modulator includes illuminating the organic crystal material via an opaque mask having a selected pattern corresponding to a desired machined pattern for the organic crystal. The light illuminating the organic crystal has a wavelength corresponding to strong absorption bands in the organic crystal and is pulsed so as to ablate the surface in correspondence with the pattern in a non-contact self-developing machining process.

    摘要： A process for repairing an electronic army wafer assembly having a short circuit between two non-insulative layers separated by a dielectric layer includes the step of selectively ablating one of the non-insulative layers so as to electrically isolate the situs of the short circuit while maintaining the electrical integrity of the underlying non-insulative layer intact. A laser beam is directed onto the non-insulative layer and scanned in a selected pattern to isolate the situs of the short circuit; the laser is further controlled such that a selected energy density is delivered to the surface to be ablated such that the underlying non-insulative layer is not damaged.

    摘要： Self-developing photoresists are developed by exposing the substrate on which they are exposed to a light beam or other energy source which is absorbed by the substrate and which raises the substrate temperature to the thermal decomposition temperature of the overlying photoresist. This exposure may be done through the photoresist layer with a light beam having a frequency to which the photoresist is substantially transparent or may be done from the backside of the substrate using a light beam which is absorbed by the substrate itself if it is sufficiently thin, or by a thin layer disposed on a transparent substrate.

    摘要： A technique for fabricating a patterned conductor on the inner surface of a transparent tube comprises providing a source of conductive material inside a hollow tube and directing actinic radiation onto the tube wall where the deposition of a conductive pattern is desired to deposit conductive material thereon. That conductive deposit may be thickened by subsequent electroless or electroplating. The result is an improved magnetic resonance sensor comprising a hollow tube having "flat" conductor coils disposed on its interior surface.

    摘要： High power, high efficiency second harmonic generation is obtained by employing a nonlinear optical crystal inside the cavity of a broadband laser. The birefringent property of the crystal and the nonlinear parametric interaction produce frequency doubling and line-narrowing simultaneously, facilitating high efficiency operation.

    摘要： The cavity of a high power laser is selectively tuned to oscillate in a relatively narrow spectral region by placing inside the cavity a birefringent KD*P filter at the Brewster angle. The degree of phase retardation introduced by the filter is controlled by applying an amplitude-variable voltage across the filter or rotating the filter about its .beta. axis. The laser may thus be line-narrowed and tuned, and may be used to generate two coherent signals at different wavelengths without need for an additional resonant cavity.
