It’s not so easy for the rest of us to see, but this humble prototype could result in cheaper and more effective lasers. Credit: Simone Bianconi, EPFL Laser technology plays a vital role in modern life, supporting everything from precise scientific measurements to advanced communication systems. It underpins technologies such as self-driving vehicles, high-speed fiber optic networks, and even tools that detect gases in the atmosphere. A research team led by Associate Professor Johann
