Developed by Rafael Advanced Defense Systems, these energy weapons direct an intense beam of light at a target and use heat to damage or destroy it.

If other countries are now using laser weapons, this begs the question, considering our enormous Pentagon budget, does the ...

In simple terms, the green laser acted more like an object, not a beam of light, creating what by all accounts could be described as a shadow. The researchers suggest this is because of "optical ...

The green laser acts like an ordinary object while the blue laser acts like illumination. The interaction between the two light sources created a shadow on a screen that was visible as a dark area ...

Typically, light passes through light without having an effect. But using a ruby crystal and specific laser wavelengths. In particular, a green laser has a non-linear response in the crystal that ...

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 ...

W. Boyd, J. S. Lundeen The technique works because the green laser (wavelength 532 nanometers) changes the way the crystal responds to some other wavelengths of light, including the 450 nm of the ...
