Lasers are used in many different domains, from communications to healthcare and even emerging quantum technologies. But making them isn’t always good for the planet. In this interview, Karim Elkhouly, Researcher at imec, explains how researchers are developing a new generation of lasers using perovskite materials, which could be produced with far less energy. Discover how these next-gen lasers work, why they matter, and how they could make future technologies more sustainable.
