A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light ...

This significant step forward in the development of photonic power converters – devices that turn laser light into electrical ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials.

Nick Stone discusses some of the many ways in which light can be used for diagnostic and therapeutic applications ...

So as you sweep through different wavelengths of light, you’ll find that there’s no wavelength of light that will only activate the M’s and neither the L’s or the S’s. So this is interesting. This ...
