Osram Opto Semiconductors' SIRILAS Laser Diode Arrays to Premier at Photonics West 2007.New Product Ideal for High Power Emission Output Applications SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- OSRAM Opto Semiconductors will premier its SIRILAS[R] laser diode A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core arrays at Photonics West 2007, in modular pumping modules produced by RayTools, maker of lasers and solutions for industrial applications. The RayTools-SIRILAS Linear Array is a simple, easy-to-use housing for the SIRILAS diode laser See laser diode. bar. Each laser diode array consists of a bar with 16 individual emitters and achieves an output of 30 Watts (W). Pumping modules with up to 10 laser diode arrays have outputs of up to 300 W. "By integrating these laser diode arrays into pumping modules, the SIRILAS Linear Array is saving time for potential customers by eliminating a major step in the development process," Ellen Sizemore, director, LED/IR marketing, OSRAM Opto Semiconductors Inc., said. "The result is a ready-to-use module with optimized cooling that can be easily incorporated in the standardized mechanical, thermal and electrical interfaces of a pumping application," she added. SIRILAS is a compact package with an innovative heat sink A material that absorbs heat. Typically made of aluminum, heat sinks are widely used in amplifiers and other electronic devices that build up heat. Small heat sinks are the most economical method for cooling microprocessors and other chips. that saves space and is cost-efficient. Integrated cooling fins, on which the laser bar is centered, provide effective water-cooling while reducing the thermal resistance. The simple design of the cooling channels minimizes the possibility of corrosion. An enclosed package protects against dust and contact, while an integrated lens produces an almost parallel beam with vertical divergence of one degree, typically. By combining multiple pumping modules, it is possible to pump high power solid-state lasers A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid such as in dye lasers or a gas as in gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers (see . These solid-state lasers are used as alternatives to CO2 lasers for material processing such as welding welding, process for joining separate pieces of metal in a continuous metallic bond. Cold-pressure welding is accomplished by the application of high pressure at room temperature; forge welding (forging) is done by means of hammering, with the addition of heat. plastic and metal. The output of a laser system can be further increased by connecting solid-state lasers in series. The SIRILAS linear arrays are best suited for applications which require a high-power line emission output, such as transversal pumping of rod lasers as well as direct applications such as plastic welding Plastic Welding is the process of welding plastic parts together. There are several techniques: Hot gas welding This is the plastic welding technique equivalent to gas welding. However, the techniques are only vaguely similar. or surface treatment. Solid-state lasers that are excited by diode laser pumping lines are much smaller than CO2 lasers and operate more efficiently. SIRILAS semiconductor lasers, with an efficiency of more than 50 percent, are ideal pumping sources because their output can be precisely tuned to the absorption lines of the solid-state laser materials. This reduces the thermal load on the solid-state laser medium, and efficiency and beam quality are improved. What's more, maintenance is easier because the laser diode arrays can be replaced individually if necessary.
