Higher harmonic detection and sensitivity to instrument drifts in trace-gas sensors

Not Accessible

Your library or personal account may give you access


We show the advantages of wavelength modulation spectroscopy for improving sensitivity in trace-gas detection. This is achieved using higher harmonic detection to probe spectral features of the absorption signal around linecenter and in line-wing region.
