the electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," said LLNL's Jeff Colvin. "At NIF, we use the high-power laser beam instead of an electron beam to make ...

Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It's a goal that sounds so fantastic, you'd be forgiven ...

A research team led by Chinese scientist “Crazy Li” has equipped small drones with the ability to emit powerful metal-cutting laser beams—a feat once thought impossible. The research ...
