The Vibrational Relaxation Processes in a CO2-N2-H2O Laser System

Abstract

Vibrational relaxation processes and data of a carbon dioxide nitrogen water laser system up to the present are surveyed. The data before 1988 are based on Taylor & Bitterman's review. The data are treated with weighted least square method to get the best fit in the form of log10K = A + BX + CX2 + DX3 and the corresponding coefficients are presented. Using these best fits of data and relaxation model with three modes and four vibrational temperatures which is based on the present work, numerical calculation results of small signal gain of GDL agree with experiments, thus eliminating the error introduced by the uncertainties of relaxation data and model.
