Abstract

Results of photoacoustic measurements of absorption of 266 nm-laser pulses (the fourth harmonics of a YAG laser) by mixtures of water vapor and nitrogen, depending on the radiation intensity (0.5–10 MW cm−2) and H2O partial pressure (0–10 mbar), are presented. It is shown that the linear absorption (in the given range of intensities) increases with H2O partial pressure in a range 0–5 mbar and remains almost stable in a range 5–10 mbar exceeding the absorption in the pure nitrogen only by two orders of magnitude.
