To achieve this reflection, thin semiconductor films are deposited on top of one another, and the laser beam is further defined by an etched channel through this stack. The thickness and ...

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 ...

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 ...

By combining AI with holographic encryption, scientists have developed an ultra-secure data protection system. Their method ...

Dual-laser system and plasma channel generation This improvement was ... of the acceleration process and optimization of beam quality. This enhanced control over the plasma channel has enabled ...

As the demand for digital security grows, researchers have developed a new optical system that uses holograms to encode ...
