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 ...

Once the laser system is online, it could help power satellites, lunar bases and even missions to Mars, according to a statement. Because laser beams remain narrow and tightly focused over long ...

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 ...

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