Paper Abstract

The CRD technique has been successfully applied in various environments since it directly provides the frequency-dependent absorption strengths of the medium under study. As mirrors with a sufficiently high reflectivity, detectors with a sufficiently fast time response, and tunable (pulsed) light sources are available, there is no intrinsic limitation to the spectral region in which CRD can be applied. In this work, cavity-ring down (CRD) technique was employed to stabilize the absorption of a cell filled with ammonia gas to 120μs pulses from a 904nm GaAlAsP semiconductor laser.
