L3 Technologies in Londonderry, N.H., was awarded a $37.5 million contract to deliver precision aiming lasers for the U.S. Navy. The precision aiming laser combines a range finder with a ballistics and environmental sensor to prepare the operator for increased likelihood of a first-round hit, according to a Pentagon announcement on Wednesday. This program supports U.S. Special Operations Command's visual augmentation systems weapons accessories program, which provides "mixed reality" headsets that allow conventional and special operations forces to run through controlled scenarios. The U.S. Army and Marine Corps have been experimenting with the headsets for several years, and plan to field them sometime in the next two years. The Navy has obligated $900,000 at the time of the award to L3 at the time of award. The deal carries a five-year ordering period, with work expected to be completed by November 2024.
Molecular vibrations lead to high performance laser Los Angeles CA (SPX) Dec 03, 2019 Lasers. They are used for everything from entertaining our cats to encrypting our communications. Unfortunately, lasers can be energy intensive and many are made using toxic materials like arsenic and gallium. To make lasers more sustainable, new materials and lasing mechanisms must be discovered. Professor Andrea Armani and her team at the USC Viterbi School of Engineering have discovered a new phenomenon and used it to make a laser with over 40 percent efficiency-nearly 10 times higher than othe ... read more
