Abstract:	A new method to experimentally determine the spectral shape of the radiation line of a tunable long-path absorption laser gas analyzer operating in a three-micron range ( = 2.5–4.5 m) on the basis of a difference-frequency generator is suggested. The method is based on measurement of the transmission function of a gas medium upon modulation of its optical thickness or pressure. Specific vibrational–rotational transitions and also optimal pressures of CO₂, N₂O, and CH₄ are recommended for carrying out experiments.
