  • Patent number: 9180550
    Abstract: The temperature of a semiconductor wafer is raised by light irradiation heating performed by halogen lamps. An infrared ray emitted from the semiconductor wafer whose temperature has been raised transmits through an infrared-transparent window made of silicon, and then is detected by an infrared camera. The infrared camera two-dimensionally detects the temperature of an entire surface of the semiconductor wafer. Based on a result of the detection obtained by the infrared camera, a temperature drop region having a relatively low temperature among the region of the semiconductor wafer is irradiated with laser light emitted from a laser light emission part. Accordingly, without rotating the semiconductor wafer, a temperature distribution can be made uniform with a high accuracy throughout the entire surface of the semiconductor wafer.

    Abstract: A compact, light weight laser beam combiner includes a pair of concentric annular shells defining an annular cavity of an annular ring resonator having an annular solid laser gain medium disposed therein. The output ends of a plurality of low power and brightness fiber lasers are coupled into the cavity of the resonator such that fiber laser beams cause the gain medium in the resonator cavity to lase and produce an annular beam of laser light. Optical elements of the resonator are operable to feed a first portion of the laser light back through the resonator cavity to support regenerative lasing of the laser medium and to couple off a second portion of the laser light in the form of a circular beam of high power and high brightness laser light. A fluid may be circulated through the resonator cavity to cool the laser medium.

  • Patent number: 6714570
    Abstract: A method for producing molecular Iodine for introduction into the laser cavity of a Chemical-Oxygen-Iodine-Laser (COIL) includes the step of preparing a solid mixture that contains a primary component and an additive component. The solid mixture is formulated to generate a gas having a high concentration of molecular Iodine when ignited. The primary component of the mixture is composed of oxidizer and fuel at a substantially stoichiometric ratio and includes at least one Iodine compound. The additive component is provided to cool the relatively high temperature gas that is created during combustion of the primary component. The result is a gas at a relatively low temperature in which most of the Iodine is present as molecular Iodine. The additive component is preferably an Iodine compound that either absorbs heat during decomposition such as Iodine Pentoxide (I2O5) or an Iodine compound that absorbs heat during sublimation such as solid Iodine.

    Abstract: There are provided chemical lasers which provide pulsed radiation in the visible or near visible (denoted hereafter as short-wavelength) range. The novel pulsed short-wavelength chemical lasers are operated by detonating an explosive mixture which contains fuel and lasants, the detonation resulting in electronically excited molecules. Lasing can be brought about by energy transfer within such molecules, or by energy transfer from such excited molecules to other molecules or to atoms resulting in the desired short-wavelength laser emission. The lasers can be operated at high pulse energies.

    Abstract: Exploding conducting film laser optical pumping apparatus. The 342-nm molecular iodine and the 1.315-.mu.m atomic iodine lasers have been optically pumped by intense light from exploding-metal-film discharges. Brightness temperatures for the exploding-film discharges were approximately 25,000 K. Although lower output energies were achieved for such discharges when compared to exploding-wire techniques, the larger surface area and smaller inductance inherent in the exploding-film should lead to improved efficiency for optically-pumped gas lasers.
