The US Navy successfully tested its new laser weapon mounted on a warship. The dramatic photo above depicts the High Energy ...

The USS Preble is the only U.S. destroyer armed with the HELIOS, which can fire laser beams to destroy fast attack craft and drones.

The pulsed nature of these lasers prevents undue heat from being created, which is common for continuous laser beams. In mode-locking, the amplitude (the distance between the crest and trough of a ...

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 ...

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

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 ...
