摘要： A method of manufacturing a laminated structure capable of being patterned into a favorable shape by preventing side etching is provided. After an adhesive layer made of ITO or the like, a reflective layer made of silver or an alloy including silver, and a barrier layer made of ITO or the like are laminated in order on a substrate with a planarizing layer which is a base layer in between, a mask is formed on the barrier layer, and the adhesive layer, the reflective layer and the barrier layer are etched at once by using the mask to form a laminated structure. As an etching gas, for example, a gas including methane (CH4) is preferable. The laminated structure is used as an anode, and an insulating film, an organic layer including a light-emitting layer and a common electrode as a cathode are laminated in order on the laminated structure so as to form an organic light-emitting device. The laminated structure can be used as a reflective electrode, a reflective film or wiring of a liquid crystal display.

摘要： A solid-state laser device which employs a bi-cylindrical lens as a focusing lens for focusing excitation light emitted from a semiconductor laser to pump a laser medium. Further, the radius of curvature of each cylindrical surface of the bi-cylindrical lens is selected such that a region of the laser medium to be pumped by a horizontal component of the pumping light and another region of the laser medium to be pumped by a vertical component of the pumping light are contained in a predetermined region of the laser medium. Thereby, output laser light which excels in transverse mode characteristics can be efficiently obtained without increasing the number of surfaces of lenses composing the focusing lens system. Moreover, there is provided a solid-state laser device which can be relatively small-sized and easily regulated.
