Stanford Team Develops Self-Cooling Silica Fiber Laser

Facebook X LinkedIn Email
STANFORD, Calif., March 22, 2021 — A Stanford University research team developed a self-cooling laser based on a silica fiber architecture. By overcoming the need for external cooling, such as with a water-based cooling system, the design charts a course for future laser-based devices capable of delivering exceptional purity and frequency stability. Applications for a self-cooling laser constructed from a silica laser fiber include the creation of advanced fiber amplifiers — useful in the all-optical transportation of information over long distances — and low-power, high-precision metrology. After...Read full article

    fiber laser
    A fiber laser is a type of laser in which the active gain medium is an optical fiber doped with rare-earth ions such as erbium, ytterbium, or neodymium. Fiber lasers generate coherent light through the process of stimulated emission, where photons are emitted in phase with an external input signal, resulting in amplified and coherent light output. fiber laser suppliers → Key features and characteristics of fiber lasers include: Fiber core: The core of a fiber laser...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
