Kinetic Model and Theoretical Calculations for Steady State Analysis of Electrically Excited CO Laser Amplifier System

Abstract

A qualitative and quantitative discussion of several aspects of electrically excited CO laser systems is presented. Topics included are molecular spectroscopy and radiative properties, molecular kinetics, and plasma characteristics. Special emphasis is on description of a steady state molecular kinetic model which has been constructed for calculation of the vibrational population distributions and resulting radiative properties for a CO laser amplifier system. The master equation for the vibrational populations is formulated, with several pumping, relaxation, cross-relaxation, and stimulated emission processes included. A computer program for cs operation with an arbitrary number of vibrational levels has been constructed for numerical solution of the master equation, and preliminary results for a variety of parameters are presented. The importance of plasma characteristics is discussed, although calculations for the electron kinetics have not yet been undertaken. Future efforts should be made to analyze the coupled system of electron and molecular kinetics on a consistent and equal basis.
