Abstract:

The results of photo-acoustic measurements of the laser pulses with a wavelength of 266 nm by water vapor mixed with nitrogen on laser radiation intensity are presented. The laser radiation intensity varies from 0.5 till 10 mW/cm2 and water vapor partial pressure changes with 0-10 mbar. It is shown that with laser intensity increase the absorption is linear for H2O partial pressure increase from 0 to 5 mbar and becomes ruther stable at H2O partial pressure increase from 5 till 10 mbar.

Keywords:

H2O absorption, UV range, laser, photo-acoustic method
