High-precision COâ isotopologue spectrometer with a difference-frequency-generation laser source
Listed in National Center for Atmospheric Research
A precision laser spectrometer for the detection of COâ isotopes is reported.
Description
The spectrometer measures the fundamental absorption signatures of ¹³C and ¹²C isotopes in COâ at 4.32 μm using a tunable mid-IR laser source based on difference-frequency generation. The spectrometer attains a precision of up to 0.02â° for 150 s of averaging.
An overall accuracy of 0.05â° was obtained when sampling various calibrated reference gases.
