Green-laser powder bed fusion technology not only enables the efficient Additive Manufacturing of pure copper and copper-based materials, but also provides novel solutions for the AM of other highly ...

Using a green laser beam, a ruby crystal, and blue light illumination, they demonstrated that light, under specific conditions, could block another light source, creating a visible shadow.

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other ...

The green laser increases the optical absorption of the blue illuminating laser beam, creating a matching region in the illuminating light and creating a darker area that appears as a shadow of ...

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 ...

Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...
