Investigation and Optimization of a Line-Locked Quartz Enhanced Spectrophone for Rapid Carbon Dioxide Measurement

We have developed a rapid quartz enhanced spectrophone for carbon dioxide (CO<sub>2</sub>) measurement, in which the laser wavelength was tightly locked to a CO<sub>2</sub> absorption line and a custom quartz tuning fork (QTF) operating at 12.5 kHz was employed. The intrinsic...
