With the concern over the changing climate and the rise of pollutants in the air, precise and effective monitoring is needed for efficient reduction of greenhouse and hazardous gases in industrial production, transportation, and propulsion.
A distributed-feedback (DFB) laser served as the TAS laser source for the investigation of H2O transport in a dry laminar jet. Wavelength Electronics’ LDTC0520 laser diode and temperature controller provided stable drive current and temperature control for the DFB laser with noise of 7.5 µA RMS, high temperature accuracy and 0.005°C stability, ensuring minimal noise was added to the photodetector after TAS.
This research shows the great potential that TAS has in the field of mass transfer and scalar field of gaseous flows.
