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 ...

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 ...

Transmitting optical information through highly distorting media has long been a challenge. Atmospheric turbulence, fog, and underwater environments distort light signals, making communication ...

Spectacular increase in brightness and decrease in pulse duration of X-ray beams are now foreseen owing to the progress made in laser–plasma interactions. At the frontier between plasmas and ...

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

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 scrambles laser beams into chaotic patterns, making decryption impossible ...

Digital currencies, communication channels, and sensitive data could be protected from cybercriminals using holograms, scientists propose.

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

The plasma channel keeps the laser pulse focused ... It enables them to comprehend the behavior of the plasma, laser, and electron beam. Cameron Geddes, director of Berkeley Lab’s ATAP Division ...
