MIRTHE Prototype Laser Spectroscopy Platform

From Photonics Spectra magazine: A new development in wireless sensor networks for monitoring trace gases and chemicals uses an infrared laser operating at 2 µm and can detect atmospheric carbon dioxide with a sensitivity of 113 parts per billion in an average time of 1 second. Gerard Wysocki, an assistant professor of electrical engineering whose Princeton group developed the sensor in collaboration with MIRTHE (Mid-InfraRed Technologies for Health and the Environment), a National Science Foundation Engineering Research Center based at Princeton, describes the sensor with assistance from postdoctoral scientist Stephen So. They demonstrated the tunable diode laser absorption spectroscopic (TDLAS) CO2 sensor at SPIE Photonics West 2010 in San Francisco. The sensor is also the subject of a news article in the March 2010 issue of Photonics Spectra magazine.
