Alfalight's New Line of High-Power Diode Laser Bars Offers High Reliability, Brightness and Efficiency.Business Editors/High-Tech Writers MADISON, Wis.--(BUSINESS WIRE)--Jan. 5, 2004 Alfalight, Inc., an innovator and manufacturer of highly efficient and reliable semiconductor diode lasers See laser diode. , today announced the availability of its ALB1 family of high-power diode laser bars. The company's Aluminum-Free Active region (ALFA) diode laser bars provide superior power conversion efficiency and high reliability, as well as low series resistance, high thermal conductivity thermal conductivity A measure of the ability of a material to transfer heat. Given two surfaces on either side of the material with a temperature difference between them, the thermal conductivity is the heat energy transferred per unit time and per unit and high facet damage threshold for all direct diode and diode-pumped solid state (DPSS DPSS Diode-Pumped Solid-State (laser) DPSS Department of Public Social Services DPSS Distributed-Parallel Storage System DPSS Datapath Synthesis System DPSS Data Processing Subsystem DPSS Digital Precision Strike Suite ) laser applications. "These new unmounted bars provide our customers with the flexibility they need to incorporate our diode lasers into their own unique package designs," said Tom Earles, chief technology officer at Alfalight. "With continuous-wave output power capability reaching 60 watts and wall-plug efficiency over 50%, Alfalight's laser bars demonstrate that they can exceed the performance of traditional laser bars." Alfalight's ALB1 series of standard laser bars offer wavelengths of 808, 915, 940 and 976 nm, with fill factors of 20, 30, 50 and 90%. The ALB1 series bars measure 10 mm long with a 1.0 mm standard cavity length; 1.5 and 2.0 mm cavity lengths are also available. The 808 nm bars have better than 1.1 watt/amp slope efficiency The slope efficiency is an important property of a laser. It is defined as the slope of the curve obtained by plotting the laser output power against the input pump power. It can similarly be defined in terms of output and input energies instead of powers. . Beam divergence The beam divergence of an electromagnetic beam is the increase in beam diameter with distance from the aperture from which the beam emerges in any plane that intersects the beam axis. is typically 10(degrees) x 35(degrees) with TM polarization polarization Property of certain types of electromagnetic radiation in which the direction and magnitude of the vibrating electric field are related in a specified way. . Availability Alfalight's new ALB1 laser bars are available now in sample or high volume quantities at all standard wavelengths. About Alfalight Alfalight, Inc. is a technology innovator and manufacturer of highly efficient and reliable high-powered diode lasers for industrial, defense, and telecommunications markets worldwide. The Madison, Wisconsin-based company's advanced Aluminum-Free Active region (ALFA) diode lasers provide industry-leading efficiency, reliability, power and brightness. Alfalight has exclusive licenses to patents that include high-power narrow-spectrum lasers, single-mode lasers, and short-wavelength lasers. To further its ongoing development efforts towards improved laser efficiency and brightness, the company recently received additional funding from DARPA DARPA: see Defense Advanced Research Projects Agency. (Defense Advanced Research Projects Agency) The name given to the U.S. Advanced Research Projects Agency during the 1980s. It was later renamed back to ARPA. . Alfalight's current high-power diode laser product line includes both multimode bars and fiber-coupled single emitters. For datasheets, or more information, please visit www.alfalight.com. |
