  • Publication number: 20150310572
    Abstract: A system, computer readable media, GUI, and apparatus are provided that are configured to generate and display an intellectual property rights profile for a media presentation. Information to be included in an intellectual property rights profile may be entered into a provided data entry template by, for example, a user or administrator of the media presentation. Uploaded documents may be added to an intellectual property rights profile and later accessed by a subsequent user. In some cases, a status, for example, complete or incomplete, may be determined for an intellectual property rights profile and an action may be initiated based on the status.

  • Patent number: 6584134
    Abstract: According to the invention, a high power diode pumped solid state laser is provided. The laser includes a first and second reflective surfaces which form an optical resonator cavity. A laser medium, particularly a Nd doped laser medium for example: a Nd:YAG, a Nd:YLF, or a Nd:YVO4 crystal is provided within the laser cavity. A fundamental frequency laser beam propagates from the front and back ends of the laser medium. The first reflective surface is highly reflective for fundamental beam. The second reflective surface is at least partially reflective for fundamental beam. The laser medium is end pumped by at least one diode pumping apparatus for example, a laser diode, or diode array, or fiber coupled laser diodes, whose wavelength matches at least one laser medium absorption band. The diode pumping apparatus is located adjacent either the front end or the back end of the laser medium, or both. The optical resonator cavity is configured to provide a laser beam diameter in the laser medium from about 0.

  • Patent number: 6246707
    Abstract: A pulsed laser preferably a tunable laser having a narrow band width is provided which has a high conversion efficiency at a high repetition rate. The laser includes a diffraction grating located in the laser's optical cavity. The optical cavity is defined by a mirror and diffraction grating or two mirrors with a diffraction grating therebetween. A tunable laser material is located within the optical cavity between the mirror and the diffraction grating. Desirably the diffraction grating is movably mounted within the optical cavity so that a beam of a presected wave length diffracted by the grating can be directed across the laser material. Optionally where two mirrors define the optical cavity, one of the mirrors or the grating or both can be movably mounted within the optical cavity. Preferable the movable grating and the movable mirror are rotatably mounted.

  • Patent number: 5936983
    Abstract: Third harmonic generated from intra-cavity frequency tripled resonator is disclosed in which a type I or type II phase matching crystal is used as the tripler. Type I phase matching is used for second harmonic generation. The resonator efficiently converts the fundamental laser frequency to its third harmonic laser beam. The laser is highly efficient with high third harmonic output stability. Overall conversion efficiency exceeds 25% and preferably is 50% or higher.
