A dual boost for optical delay scanning

Various applications of pulsed laser sources rely on the ability to produce a series of pulse pairs with a stepwise increasing delay between them. Implementing such optical delay scanning with high precision is demanding, ...

Laser creates a miniature magnetosphere

Magnetic reconnections in laser-produced plasmas have been studied to understand microscopic electron dynamics, which is applicable to space and astrophysical phenomena. Osaka University researchers, in collaboration with ...

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. ...
