Abstract:

A unique differential photoacoustic system is described along with water vapor absorption measurements made at HF laser lines. The photoacoustic system is capable of determining absorption coefficients to .005km. Comparisons of the data with calculated values based on a modified Lorentz profile with an augmented line wing and the latest atmospheric absorption line compilation showed good agreement for all laser lines at high pressures N700 torr with some discrepancies at lower pressures.
