Recent Advances of Trace Gas Sensors based on Infrared Semiconductor Lasers: Global Opportunities and Challenges
The detection, quantification and monitoring of trace chemical
species in the gas phase find applications in such diverse fields as
environmental monitoring, industrial process control, and medical
diagnostics. This talk will focus on recent advances in the development
of sensors based on infrared semiconductor lasers for the detection of
trace gas species. Through the use of sensitivity enhancement schemes
minimum detectable absorbances in the range from 10-4 to 10-5 can be
realized. Several recent examples of real world applications to
environmental monitoring atmospheric chemistry and in medicine will be
described. (For further details see Rice University Laser Science Group
