Abstract
Precision limitations of Tunable Diode Laser Spectroscopy (TDLS) are analyzed in relation to precise line-shape measurements such as baseline, optical zero, nonlinearity, laser noise, etc.) to affect experimental accuracy. Analytical expressions were derived for different error sources. An experimental procedure and data processing algorithm is proposed to minimize the error of line-shape parameters determination. It was shown that relative intensity measurements can be accurate within 0.3%.
