Integrated path detection of CO2 and CH4 using a waveform driven electro-optic single sideband laser source



Gerd A. Wagner, Stephen E. Maxwell, David F. Plusquellic


Integrated path concentrations of ambient levels of carbon dioxide and methane have been measured during nighttime periods at NIST, Boulder (CO, USA), using a ground-based, eye-safe laser system. In this contribution, we describe the transmitter and receiver system, demonstrate measurements of CO2 and CH4 in comparison with an in situ point sensor measurement using a commercial cavity ring-down instrument, and demonstrate a speckle noise reduction method
