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°), ...

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 ...

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 ...

It is powerful enough to pass through the mirrors as a laser beam. Lasers can be used to transmit a charge between the laser transmitter and a receiver. The distributed laser-charging method ...
