Frequency Combs Advance Biomedicine

Facebook X LinkedIn Email
DENVER, June 15, 2012 — Laser frequency combs, first a curiosity but now a practical research tool, are moving beyond physics and optics to advance biomedicine by helping evalulate a novel instrument that kills harmful bacteria without liquid chemicals or high temperatures. Generated by ultrafast lasers, frequency combs precisely measure individual frequencies of light. As with many new measurement tools, the laser frequency comb seemed at first an oddity but has found more practical uses than originally imagined. Researchers at JILA, operated jointly by the National Institute of Standards and Technology...Read full article

    frequency comb
    A frequency comb is a precise and regular series of equally spaced spectral lines, or frequencies, that are generated with great accuracy. The term "frequency comb" is often associated with the Nobel Prize-winning technique known as frequency comb spectroscopy, developed by John L. Hall and Theodor W. Hänsch in the 1990s. The technology has since become a powerful tool in various scientific and technological applications. Key points about frequency combs: Origin and development: The...
