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 ...

The laser shadow effect is a consequence of optical nonlinear absorption in the ruby. The effect occurs because the green ...

To create this effect, the team directed a high-power green laser through a ruby crystal and illuminated it perpendicularly with a blue laser. When the green laser interacted with the ruby ...
