As well as being important for basic science, the work could have applications in laser fabrication and imaging. The light-shadow experiment began when physicists led by Raphael Akel Abrahao sent a ...

Chemically modifying the semiconductors allowed for a shift into the green part of ... element to divide light into different wavelengths, allowing multiple laser beams to combine.

This new type of laser emits a green laser beam consisting of short light pulses. For now, this is mainly a scientific breakthrough, but with future development the laser could potentially be ...

The effect occurs because the green laser increases the optical absorption of the blue illuminating laser beam, creating a matching region in the illuminating light with lower optical intensity.
