The process is only about 48% efficient, meaning that IR leaks out along with the green light. The better quality DPSS laser pointers include a quality IR filter to remove it; cheaper ones often ...

When the green laser interacted with the ruby, it altered the crystal’s optical properties, increasing its absorption of the blue light and casting a visible shadow in the shape of the green laser.

Much of our waste is far too valuable to simply be incinerated. If it is recycled in a carefully controlled way, not only can thermal energy 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 ...

Flowing quantum dot solutions enhance heat dissipation, enabling stable high-speed pulsed operation and tunable color output for next-generation optical devices.

But there’s a new light in this rainbow of solutions: green light. With promises of reducing inflammation and fading pesky dark spots paired with the mesmerizing effect of bathing skin in a Brat ...

Red-light therapy is getting the green light in some health circles, but it’s early yet to say whether that’s a good thing. The treatment, a type of light therapy called photobiomodulation ...
