Abstract

In the last years, laser-based spectroscopic techniques for trace gas detection on the ppb level have received increasing attention. Cavity Leak-Out Spectroscopy (CALOS) is a fast, accurate and universal method for online measurement of absolute trace gas concentrations,1 e.g., the concentration of small hydrocarbons in ambient air samples.2
