For example, when an infrared laser with an 800-nanometer wavelength hits the metalens, visible light at 400 nanometers emerges, focused to a sharp point.

The image reveals over 2,500 galaxies, many of which are seen as they were during the first billion years of cosmic history.

What's more, even in theory, visible wavelengths of light emitted by biological processes ought to be so faint that it's easily swamped by the intense shine of ambient electromagnetic waves in the ...

WASHINGTON — NASA’s Perseverance rover has detected the first aurora at Mars that's visible to the human eye, good news for future astronauts who can savor the view on the red planet. European ...

Using this method, they were able to up-convert infrared light of wavelength around 1550 nm to 622 nm visible light. The output light wave can be detected using traditional silicon-based cameras.
