Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers at Chalmers University of Technology in Sweden have scored a world first with their solution to make microcombs ten times more efficient. Their breakthrough opens the way to new discoveries in space and healthcare and paves the way for high-performance lasers in a range of other technologies.
