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

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 ...

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°), ...

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 ...

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 ...

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 ...

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.
