Searching for TDEs in infrared light offers an alternative to optical and X-ray surveys. When a black hole tears a star apart, the TDEs should generate infrared light.

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.

Earth's heat generates infrared light on its own, which is then scattered throughout the atmosphere, making it virtually impossible for astronomers to see using infrared from ground-based telescopes.

UNSW researchers have made a breakthrough for renewable energy production, demonstrating for the first time the ability to produce electricity from radiant infrared heat sources. The emerging ...

A green laser pen works according to this principle: infrared light goes through a high-quality crystalline material and generates light of half the wavelength—in this case green light.
