Presented at ICALEO 2005
Aluminum alloys are very popular in the industrial world as structural materials, mainly due to their high strength to weight ratio. Unfortunately, due to their material properties, aluminum alloys are some of the hardest metals to be laser welded successfully and very high laser power is usually required. In this study, we explore the capability of using a 300 W fiber laser for high speed aluminum...$28.00

Presented at ICALEO 2005
NIST has been tasked by DARPA to provide wall plug efficiency and spectral measurements of high-power high-efficiency laser diodes and arrays for DARPA?s Super High Efficiency Diode Sources (SHEDS) program. To meet the needs for this project, the Optoelectronics Division has developed a new laboratory at NIST to measure electrical power, optical power, wavelength and line width, and junction temperature for lasers supplied by project participants. We describe a novel flowing-water optical power meter (FWOPM) that we have developed to meet the u...$28.00

By incorporating a transverse Bragg grating into a large-area laser, the optical modes of the laser can be designed to improve the efficiency compared to traditional index-guided lasers. The resulting transverse Bragg resonance (TBR) waveguide can be designed to have a single lateral mode that is distributed throughout t...$28.00
