In an era demanding ever-smaller, more efficient, and higher-performing light sources, particularly in the short-wave ...

The far-field pattern and its intensity profile during laser oscillation (Fig. 3 (c), (d)) show that the oscillation was achieved with an extremely narrow beam divergence angle (of as low as 0.05°), ...

Fast communications could speed up science on the asteroid mission. A NASA laser just fired successfully in a deep-space test. On Nov. 14, NASA picked up a laser signal fired from an instrument ...

During an LPI procedure, a doctor will use a laser beam to create a tiny hole in the iris. The hole allows the fluid to flow toward the drainage angle, which relieves pressure. Studies have found ...

Scientists have demonstrated in a first that a powerful laser beam directed at the sky can create a “virtual lightning rod” that can divert the path of lightning strikes. The research ...

The groundbreaking tractor beam, made of a hollow laser beam (a laser bright around the edges and hollow in the centre), was able to move particles 0.2 mm in diameter distances up to 20 cm (7.87 ...

As the crowd counted down from five in unison, Fox smashed the button, sending a giant purple laser beam into the night sky above Golden 1 Center. Take a look: .@vivek and @swipathefox light the ...

Israel expects its “Iron Beam” laser defense system to be operational within one year, saying it will bring “a new era of warfare” as it engages in a war of drones and missiles with Iran ...

This continued until there were enough phonons to make up a laser-like beam. Several research groups had tested similar designs before. But Jing and his colleagues added an electrode right below ...

Imagine the impact when a 100000000zw laser hits earth for just 1 second. Samuel Alito Comment During Obamacare Supreme Court Hearing Sparks Laughter Millionaire Tax Would Generate About $400 ...

An effort led by the Naval Postgraduate School (NPS) used AI to make laser weapons ... confirm its angle relative to the observer, seek out the weak spot, and fix the beam on that spot.
