Determination of Absorption-line Parameters Using 2-tone Frequency-modulation Spectroscopy With Diode-lasers

Kauranen, P and Avetisov, V. G (1994) In Optics Communications 106(4-6). p.213-217
Abstract
Accurate determination of line parameters from weak absorption using two-tone frequency-modulation spectroscopy (TTFMS) with a GaAlAs diode laser is demonstrated. The air-broadening of three oxygen A-band lines is determined, using a least-squares fit. For a peak absorption of 1.3 x 10(-3) the deviation between the experimental and the fitted spectrum is less than 1%. The fitting procedure is successfully tested on absorptions as small as 4.5 x 10(-5).
