A new “superradiant” laser that traps 1 million rubidium atoms into a 2-cm space between two mirrors produces a deep-red laser beam that could boost the performance of the most advanced atomic clocks, communications and navigation systems, and space-based astronomical instruments. Scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder, developed the prototype, which has the potential to be 100 to 1000 times more stable than the best conventional visible lasers. The research appeared in the...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
