For measuring water vapor, shot-noise limited sensitivity has been achieved by a careful choice of system components and data processing. For measuring formaldehyde, a selective sample modulation exploiting the Stark effect has been used to greatly improve the sensitivity.Water Isotopic RatioDiode LaserLaser SpectroscopyFormaldehydeStark EffectDyroff Christophauth1327850BOOK9910346927703321Tunable Diode-Laser Absorption Spectroscopy for Trace-Gas Measurements with High Sensitivity and Low Drift3038178UNINA
