Abstract
High-resolution Fourier-transform spectrometry is presently used, in conjunction with a specially designed multipath absorption cell, to obtain molecular absorption spectra in the 1.30-1.32 micron range for water vapor and isotopically substituted water vapor. A range of water vapor number densities, including the foreign gas-pressure broadening of water vapor by air, were studied in order to extract line-shape parameters required for atmospheric laser-propagation modeling. Molecular line shape parameters are summarized for the 1.3-micron region, and estimates are presented for ground-to-space laser propagation at several representative wavelengths. The majority of line strengths are smaller than the corresponding values in the USAF Geophysics Laboratory HITRAN molecular-parameter data base.
