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 ...

Behold–here lies our first chance to bounce the beam away from it’s expected target and toast a nice hole in the wall. To avoid taking our chances, the laser cutter must operate in a fully ...

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 ...

Its functionality is basic compared to dedicated stud sensors that can indicate the center of a beam ... laser reference line. So as not to leave marks or holes behind when attached to a wall ...

Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called photons. Notable examples include laser-powered ...
