Grisar, R.Schmidtke, G.Tacke, M.Restelli, G.2022-03-082022-03-081989https://publica.fraunhofer.de/handle/publica/317016This volume contains the papers presented at the Second International Symposium on Monitoring of Gaseous Pollutants by Tunable Diode Lasers which was held on October 17 - 18, 1988 at Freiburg, Federal Republic of Germany. The volume is grouped in five sections: Atmospheric Trace Gas and Exhaust Gas Analysis: Lead Chalcogenide Diode Laser Development, Components and Techniques, Special Applications, Photoacoustics. The contributions treat extensively the present state of the art in the above fields. In particular, a worldwide survey over lead chalcogenide laser development in the three main laboratories working in this field is given and most recent results on the application of tunable diode lasers in immission and emission analysis are presented. Further more, the development of some advanced components as White cells and computer control and on prospective techniques such as high frequency modulation techniques is reported on.enAbgasanalyseatmosphärische SpurengasanalyseAtmospheric Trace Gas AnalysisBlei-Chalkogenid-DiodenlaserDiode Laser SpectrometerDiodenlaserspektrometerExhaust Gas Analysisfrequency modulation spectroscopyFrequenzmodulationsspektroskopieLead Chalcogenide Diode Lasermolecular beam epitaxyMolekularstrahlepitaxiephotoacousticPhotoakustik621conference proceeding
