摘要： A composite photonic structure element comprises a photonic crystal and multilayer films. The photonic crystal is formed by alternately laminating a plurality of sets of an active layer having a nonlinear effect for converting a fundamental wave into a second harmonic and an inactive layer having no nonlinear effect, and is constructed such that the energy of the fundamental wave coincides with a photonic bandgap end. Each of the multilayer films is formed by laminating a plurality of sets of two kinds of thin films having different refractive indexes and reflects the fundamental wave. The multilayer films are connected to both ends of the photonic crystal. The fundamental wave enters one of end faces and is reciprocally reflected between resonators having the multilayer films, so that the intensity of the fundamental wave is enhanced within the photonic crystal. The fundamental wave is converted into a second harmonic in the active layer, and the second harmonic is taken out from the other end face.

摘要： At least one surface of a plate member made of ZnSe has a concave-and-convex structure in which a projecting section and a groove section are formed at a spatial cycle equal to or lower than the wavelength of carbon dioxide laser light to thereby provide a substrate body. On a surface of the concave-and-convex structure, an antireflection film is layered that has a lower refractive index than that of ZnSe to carbon dioxide laser light. By this configuration, the polarization state of transmitted carbon dioxide laser light is converted from a linear polarization to a circular polarization or the like.

摘要： Fine wirings are made by a method having the steps of painting a board with metal dispersion colloid including metal nanoparticles of 0.5 nm-200 nm diameters, drying the metal dispersion colloid into a metal-suspension film, irradiating the metal-suspension film with a laser beam of 300 nm-550 nm wavelengths, depicting arbitrary patterns on the film with the laser beam, aggregating metal nanoparticles into larger conductive grains, washing the laser-irradiated film, eliminating unirradiated metal nanoparticles, and forming metallic wiring patterns built by the conductive grains on the board. The present invention enables an inexpensive apparatus to form fine arbitrary wiring patterns on boards without expensive photomasks, resists, exposure apparatus and etching apparatus. The method can make wirings also on plastic boards or low-melting-point glass boards which have poor resistance against heat and chemicals.

摘要： A laser beam condensing device which can be manufactured at low cost by using reflecting mirrors which can be machined at low cost. The device is capable of condensing a laser beam to a high energy density while eliminating any optical path difference, even if the optical axis of the incident beam strays. This device includes a first and a second reflecting mirror. An incident laser beam is deflected by these mirrors in the same direction. One of the two mirrors is a toroidal mirror, while the other is a spherical, cylindrical or toroidal reflecting mirror. The mirror surfaces of the two reflecting mirrors are machined so that the second reflecting mirror can cancel out any wave front aberrations of the laser beam reflected by the first reflecting mirror.
