Researchers Find More Efficient Way To Steer Laser Beams

For many practical applications involving lasers, it’s important to be able to control the direction of the laser beams. Just ask Han Solo, or the captain of the Death Star. Researchers from North Carolina State University have come up with a very energy-efficient way of steering laser beams that is precise and relatively inexpensive.

“In many cases, it is much easier to redirect a laser beam at a target than to steer the laser itself. We intended to develop a way to do this efficiently and without moving anything,” says Dr. Michael Escuti, an associate professor of electrical engineering at NC State and co-author of a paper on the research. “We also wanted to be able to steer the beams over a wide range of angles, which is important for practical applications.”
