Engineers find a way to win in laser performance by losing
St. Louis MO (SPX) Oct 20, 2014 - Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis. To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers at Washington University in St. Louis have shown a new way to reverse or e ... more
