  • Patent number: 9065241
    Abstract: An inventive composite optical gain medium capable includes a thin-disk gain layer bonded to an index-matched cap. The gain medium's surface is shaped like a paraboloid frustum or other truncated surface of revolution. The gain medium may be cryogenically cooled and optically pumped to provide optical gain for a pulsed laser beam. Photons emitted spontaneously in the gain layer reflect off or refract through the curved surface and out of the gain medium, reducing amplified spontaneous emission (ASE). This reduces limits on stored energy and gain imposed by ASE, enabling higher average powers (e.g., 100-10,000 Watts). Operating at cryogenic temperatures reduces thermal distortion caused by thermo-mechanical surface deformations and thermo-optic index variations in the gain medium. This facilitates the use of the gain medium in an image-relayed, multi-pass architecture for smoothed extraction and further increases in peak pulse energy (e.g., to 1-100 Joules).

  • Publication number: 20140359442
    Abstract: The present invention is to provide a method applicable to an electronic device having two programs stored therein and a display including a foreground and a background for creating a three-dimensional visual effect in the display, wherein one program presents a first image in the foreground in a prominent state and plays a sound corresponding to the first image, and the other program presents a second image in the background in a state other than the prominent state. When the electronic device determines that the second image is clicked, the electronic device switches the second image from the background to the foreground, changes the second image to the prominent state, plays a sound corresponding to the second image, switches the first image from the foreground to the background, changes the first image to the state other than the prominent state, and stops playing the sound corresponding to the first image.

  • Publication number: 20140200309
    Abstract: Disclosed is a method for preparing a vinyl chloride seed, comprising adding a vinyl chloride monomer, an emulsifier and a polymerization initiator to an aqueous medium, homogenizing droplets using a homogenizer pump, and polymerizing the homogenized droplets. The method provides a more stable latex by minimizing residual monomers by performing polymerization after adding a higher aliphatic alcohol serving as a monomer absorption enhancer and then performing homogenization, and additionally, improves productivity and reduces amount of scale generated by increasing the efficiency of monomer consumption during polymerization. Further, by applying the vinyl chloride-based seed to seed emulsion polymerization of vinyl chloride resins, polymer reactivity is improved, the reaction time of the seed emulsion polymerization is effectively reduced, the sizes of small and large particles are controlled and the particle diameter of the vinyl chloride resin is thus controlled.

  • Patent number: 8704198
    Abstract: Extreme ultraviolet radiation is generated based on high-order harmonic generation. First, a driver pulse is generated from a drive laser. Second, the infrared driver pulse is passed through a second harmonic generator with an output wavelength in the range from 400 to 700 nm. Third, the pulse is then passed through a gas medium, which can be inside a resonant cavity, to generate a high-order harmonic in the form of extreme ultraviolet radiation.

  • Patent number: 8390921
    Abstract: Seed light pulses and pump light pulses are generated; the seed light pulses are preferably chirped; and both are directed into an enhancement cavity at a full repetition rate. The enhancement cavity defines a closed optical path that contains a nonlinear medium that provides phase matching at a wavelength different from both the central seed wavelength and the central pump wavelength. The generation of the pump light pulses and the seed light pulses are synchronized to pass the seed light pulses through the nonlinear medium simultaneously with the pump light pulses to parametrically amplify the seed light pulses in the nonlinear medium to produce an amplified signal pulse and idler pulse. Increased conversion with low average pump power can be achieved, as well as gain bandwidth enhancement approaching octave-spanning levels.

  • Publication number: 20120301423
    Abstract: The present invention relates to derivatives of ?,?-disubstituted amide compounds which comprise a substituted aryl at the ? carbon such that the substituent provides a means for attachment or incorporation of the compound to or in a polymer. The provision of such a substituent on the aryl has surprisingly been found not only to permit attachment to or incorporation in a polymer but also retention of useful antifouling activity. In embodiments, the substituent is selected from hydroxyl, ethers, es ters, carboxyls, alkylsilyls and alkenyls. Experiments demonstrate that antifouling activity can be as good or better as the corresponding unsubstituted compound and that polymers functionalised so as to include or be formed from the substituted compound can be used to reduce settlement.
