Abstract :
Nonintrusive, species-selective and linear detection of trace gases is implemented with a novel intracavity laser absorption method. A first experimental realisation demonstrates a sensitivity of 3×10 9 molecules of methane, which exceeds that of gas chromatography by two orders of magnitude
