Alfalight Delivers High Power, High Reliability to 915 nm, 940 nm and 976 nm Diode Lasers; Broadened Product Portfolio for Industrial and Telecom Applications to be Showcased at Photonics West 2006.MADISON, Wis. -- Alfalight, Inc., an innovative manufacturer of highly efficient and reliable high-power diode lasers See laser diode. , today introduced several new fiber-coupled diode laser pumps. These include a 7 watt, 915 nm uncooled device for industrial fiber laser applications; a 4 watt, 940 nm uncooled device for low-cost telecommunication optical amplifiers A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. ; and a 2.5 watt 976 nm thermoelectrically-cooled device, aimed at high-power telecommunications applications. Alfalight will exhibit their newly-expanded diode laser product line and industry-leading technology in booth 245 at Photonics West 2006 in San Jose, California San Jose (IPA: /ˌsænhoʊˈzeɪ/) is the third-largest city in California, and the tenth-largest in the United States. It is the county seat of Santa Clara County. (January 24-26). "The common theme across Alfalight's entire diode laser product line is high reliability," said Ron Bechtold, vice president of Sales and Marketing at Alfalight. "Whether our pump solutions are being used for industrial fiber lasers or for cladding-pumped optical amplifiers in 'triple play' telecom applications, our customers benefit from our advanced packaging, superior reliability, and cost-effective solutions." Product Details --The Alfalight AM6-915A-10-708 (7 watt, 915 nm) is an uncooled multimode 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 in a small footprint 6-pin package. The package incorporates a thermistor Thermistor An electrical resistor with a relatively large negative temperature coefficient of resistance. Thermistors are useful for measuring temperature and gas flow or wind velocity. for temperature monitoring. The high output power provides reduced cost per watt, allowing companies to build cost-effective diode-pumped systems. --The Alfalight AM6-940A-20-408 (4 watt, 940 nm) is an uncooled multimode device in a 6-pin package, also incorporating a thermistor for temperature monitoring. This device offers exceptional reliability and is qualified for telecom applications. --The Alfalight AM4-976A-10-253 (2.5 watt, 976 nm) is a cooled multimode laser in a 14-pin butterfly package with an integrated thermoelectric ther·mo·e·lec·tric also ther·mo·e·lec·tri·cal adj. Characteristic of, resulting from, or using electrical phenomena occurring in conjunction with a flow of heat. cooler (TEC), thermistor, and photodiode A light sensor (photodetector) that allows current to flow in one direction from one side to the other when it absorbs photons (light). The more light, the more the current. Used to detect light pulses in optical fibers and other light-sensitive applications, it works the opposite of a . This device provides a half-watt more than Alfalight's previous offering and is qualified for telecom applications. It is an ideal solution for pumping the narrow absorption peak in erbium-ytterbium-doped fiber in amplifier and pulsed fiber laser applications. All products are hermetically her·met·ic also her·met·i·cal adj. 1. Completely sealed, especially against the escape or entry of air. 2. Impervious to outside interference or influence: sealed in an epoxy-free, all-metal package and power is delivered through a 105 micron, 0.15NA fiber pigtail A Fiber Pigtail is a single-fiber cable, usually short length, that has an optical connector on one end and a length of exposed fiber at the other end. The exposed fiber of the pigtail may be spliced to one fiber of a multifiber trunk, i.e. . Availability
