Nearly 50-meter laser experiment sets record in university hallway

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that's what happened in UMD's Energy Research Facility, an unremarkable looking building on the northeast ...

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 ...

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. ...
