New laser breakthrough to help understanding of gravitational waves

Gravitational wave scientists from The University of Western Australia have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test fundamental ...

Scientists invent topological-cavity surface-emitting laser

Semiconductor lasers are the most widely used lasers due to their compact size, high efficiency, low cost and wide spectra. But they suffer low output power and low beam quality—two specifications difficult to improve simultaneously. ...

Riding a laser to Mars

Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber ...

Nuclear scientists hail US fusion breakthrough

Nuclear scientists using lasers the size of three football fields said Tuesday they had generated a huge amount of energy from fusion, possibly offering hope for the development of a new clean energy source.
