Abstract

Optical parametric oscillators (OPOs) with broadband output in the mid-infrared are well suited for high resolution, high sensitivity multi-species infrared spectroscopy. Applications often require remote delivery, either over open-paths or via fiber delivery to inaccessible environments. Here we explore a flexible, easy to use, high-resolution technique in a challenging, spectroscopically cluttered landscape containing both narrow line-like and broad continuum-like features. Quantitative, high resolution, time-resolved, simultaneous measurement of water, methane, methanol and C2H7NO (MEA) concentrations are performed via fiber delivery of the OPO light. Detection limits, and the impact of the presence of one species on the others, are also explored.
