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 ...

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 ...

Lacking a vault door to drill, they used a powerful laser, delidding the IC and pulsing different areas of it with the beam. How do you know when exactly to pulse? For that, they took power ...

Our approach uses laser beams to process multiple possibilities simultaneously, dramatically increasing computing power," says Dr. Isaac Nape, the Optica Emerging Leader Chair in Optics at Wits.
