In a new study, researchers at Osaka University have created the world's first compact, tunable-wavelength blue semiconductor ...

This would ideally be achieved by just a single wavelength beam combining system, which would bring into sight more compact blue-laser copper processing systems, adds Ohno. Prototype machines ...

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

Researchers from Japan have developed tuneable blue semiconductor lasers initiating practical far-UV light sources.

Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various ...

Brookhaven researchers have revealed that a laser beam can cast a shadow through nonlinear optical processes, challenging ...
