Numerical solutions are given for vibrational population inversions created in CO2-N2-He mixtures due to shock wave heating of a cold gas. The results indicate that population inversions between the (040) and (001) energy levels of CO2 and, to a lesser degree, between the (200) and (001) levels, can be created in the vibrational nonequilibrium flow behind a normal shock front. The properties of these inversions as a possible laser medium are assessed; the results indicate that the laser properties of this shock-induced nonequilibrium flow are not as promising as those of lasers operating on the principle of rapid expansions.

Results are given for equilibrium properties behind incident and reflected normal shock waves in CO2-N2-He mixtures wherein the gas may be vibrationally excited but not chemically reacting. A rapid numerical iterative analysis is described, and the results are given in simple graphical form for convenient use in shock tube and shock tunnel experiments. The results are anticipated to be of particular use in determining reservoir conditions for shock tunnel experiments dealing with vibrational population inversions in rapidly expanding mixtures.

Gasdynamic Lasers: An Introduction is a 12-chapter introductory text to major development generations of gasdynamic lasers, focusing on their underlying physical and fundamental aspects. The opening chapters discuss the basic detailed physical phenomena that ultimately are responsible for producing gasdynamic laser action and the methods of calculating the performance of these devices. These topics are followed by a chapter on confirmation of the performance calculations through arc and shock tunnel experiments. The discussion then shifts to vibrational relaxation process behind normal shock waves in CO2-N2-He mixtures and assesses their population inversions occurring in the nonequilibrium flow. Other chapters explore the concepts of downstream mixing and optical cavity in gasdynamic lasers, as well as the laser beam extracted from these devices. A systematic study of aerodynamic windows that use supersonic flow across the aperture is presented in the concluding chapters, along with the phenomena associated with gasdynamic laser diffusers. This introductory text will be of great value to professional scientists and engineers, as well as to students and workers in the field who are interested in interdisciplinary applied science.
