COMPACT JILA SYSTEM STABILIZES LASER FREQUENCY

摘要

A compact, inexpensive method for stabilizing lasers that uses a new design to reduce sensitivity to vibration and gravity 100 times better than similar approaches has been demonstrated by scientists at JILA in Boulder, Colo. JILA is a joint institute of the NIST and the University of Colorado at Boulder. The method, described in the July 15 issue of Optics Letters,* stabilizes laser light to a single frequency, so that it can be used as a reliable reference oscillator for technologies such as optical clocks and light-based radar (lidar). The new stabilizer design performs better than similar systems of comparable size and is much smaller and less expensive than the best-performing systems, according to physicist John Hall, a co-author of the paper.
