Abstract
A room-temperature-operating vertical external cavity surface emitting laser is applied around to intracavity laser absorption spectroscopy analyzed by time-resolved Fourier-transform interferometry. At an equivalent path length of , the high-resolution spectrum of the semiconductor disk laser emission covers simultaneously. A noise-equivalent absorption coefficient at averaging equal to per spectral element is reported for , the longest path length employed.
