Abstract

A large diameter, diaphragmless shock tube equipped with a supersonic nozzle section has been newly developed in order to study experimentally various basic characteristics of the gas-dynamic laser. During a series of recent experiments with such a device the population inversion of the vibrational levels of CO2 in a supersonic flow of shocked gaseous mixture of CO 2-N2 was successfully achieved. In addition, an analysis of the pulsed 10.6-μm laser radiation (single-shot) generated by this population inversion is provided.
