Physicists have engineered a significantly more stable laser, an advance which could lead to better atomic clocks for equipment, such as GPS satellites, and physics experiments.
Researchers at the JILA, a joint institute of the National Institute of Standards and Technology and the University of Colorado, have built a prototype of a superradiant laser using 1 million rubidium atoms. Their work was described in a paper published in Nature yesterday.
Using a different structure than traditional lasers, the researchers believe they can build a laser which is 100 to 1,000 times more stable. These lasers could be used in … Read more
