Abstract:
In this paper we present a description of a spectrophotometer complex based on a multipass 110-m-length gas chamber aimed at studying energy losses of laser radiation of IR, visible, and UV regions in molecular gas media and in air. We also discuss key aspects of a technique for measuring absorption coefficients. Measurements of the absorption of an Nd:YAG laser emission by air at the fundamental frequency and its second and fourth harmonics are presented.
