Scientists propose solution to long-puzzling fusion problem

The paradox startled scientists at the U.S Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) more than a dozen years ago. The more heat they beamed into a spherical tokamak, a magnetic facility designed ...

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. ...
