In a new study, researchers at Osaka University have created the world's first compact, tunable-wavelength blue semiconductor laser, a significant advancement for far-ultraviolet light technology ...

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 ...

When the green laser enters the ruby, it locally changes the material response to the blue wavelength. The green laser acts like an ordinary object while the blue laser acts like illumination.

Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical imaging ...

When the green laser enters the ruby, it locally changes the material response to the blue wavelength. The green laser acts like an ordinary object while the blue laser acts like illumination. The ...

A research team at Osaka University developed a compact microresonator device that generates vacuum ultraviolet (VUV) light ...
