Absorption Line Filter Window and Method for Velocity Measurements by Light Scattering

Researchers at Princeton University have developed a novel technique for measuring the velocity of air flow by observing velocity-related frequency shifts in light scattered from moving air molecules or particles suspended in the moving air. Scattered light is passed through an absorption line filter window gas cell with a notch type attenuation...

Remote Detection of Molecular Species Using Air Laser

Researchers at Princeton University have developed a novel method of lasing in air that could be used for long range detection of molecular species, such as atmospheric pollutants or chemicals. Princeton is currently seeking industrial collaborators to commercialize this technology. The technology employs the use of a near infrared laser...
