Abstract

A method of simultaneous heating and temperature measuring of a gas absorber by means of an ir CO2 laser is proposed and tested. The proposed method is relatively simple and direct. In this experiment the temperature on the beam axis as a function of the beam intensity, the beam radius, and the absorber mixture is measured. A good agreement is obtained between the experimental results and theoretical predictions based on the level scheme and the physical characteristics of the absorber. The temperature measurement proposed in the present paper is an additional experimental tool in investigating excitation processes in the ir region.
