Abstract:
A laser optoacoustic spectrometer (LOAS) based on a frequency tunable dye laser with an absorption cell positioned inside the resonator has been developed. The LOAS is characterized by the high sensitivity according thee 4Ч10-9 cm-1 limit absorption coefficient at the high spectral resolution. Both the recording regimes of the absorption spectrum and its derivative have been realized. The parameters of the weak atmospheric water vapor absorption lines have been measured with the signal-to-noise ratio of 1500.
