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 ...

Israel's Iron Beam laser air defense system is set to become operational in the second half of 2025, and now the "National ...

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 ...

In this area researchers have now demonstrated a way around this, by using curved channels for the laser beams (paywalled paper) which inject the laser beam into the continuous cavity. Schematic ...

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 ...

Iron Beam, utilizing a 100 kW laser beam, will enable the destruction of a wide range of targets. Interestingly, a single ...

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 ...
