Abstract: Some limitations of tunable diode laser spectroscopy caused by laser noise, drifts and general interferometric effects are discussed together with novel signal processing strategies to cope with stability problems. The importance of fast switching between ambient and background measurements is emphasized and the application of additional sample modulation is proposed to improve system performance for trace gas analysis.
