Tractor Beam Becoming a Reality

Facebook X LinkedIn Email
CANBERRA, Australia, Sept. 21, 2010 — Using a specially designed laser beam, researchers at the Australian National University (ANU) have developed the ability to move particles over large distances. Professor Andrei Rode’s team from the Laser Physics Center at ANU have developed a laser beam that can move very small particles up to distances of a meter and a half using only the power of light. Whilst the laser beam won’t work in the vacuum of space, the breakthrough has many important uses on Earth, such as the assembly of micro machines and electronic components. Rode said his team used the hollow...Read full article
