REO High Damage Threshold Solid State Laser Mirrors.jpg

Reo produces reflectors for pulsed solid-state lasers that operate at 1064, 532, and 355 nm, as well as with multispectral laser systems. According to the company, the mirrors provide a combination of high damage threshold, ultralow scatter, good wave-front performance, high environmental stability, and rugged mechanical durability. They are suited for demanding applications such as industrial materials processing, intracavity laser use, and high-energy research lasers. The mirrors are made using ion beam sputtering technology to produce fully densified coatings that are resistant to environmental contaminants, fabrication techniques that minimize subsurface damage, and rigorous control of contamination at all steps. Custom-made mirrors have typical specifications of 99.99% reflectivity, λ/20 flatness (at 633 nm), 10-5 surface quality, and scatter loss of 1 ppm. The units are made in a range of sizes and shapes, with typical diameter of 0.25 to 10 in, and from most substrate materials, including fused silica, optical glasses, Zerodur, and Pyrex.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.

France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.

One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
