Novel Long-Wave Infrared Transparent Thermoset Polymers for Optical Components and Imaging Systems
This invention is new polymeric materials with improved Long Wave Infrared (LWIR) transmission as demonstrated by IR spectroscopy and IR thermal imaging. A one mm thick polymer film demonstrated transmittance with an LWIR camera in the 7.5-13 micron regime. The polymer is a thermoset and can be fabricated into windows, lenses, and prisms using simple...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
