Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Allowing gas detection and identification in just seconds, new approach using a coherent control strategy offers promise for real-time monitoring in environmental, health and industrial applications ...

Researchers have developed a method for quickly detecting and identifying very low concentrations of gases, which, could form the basis for highly sensitive real-time sensors for applications such as ...
