Application of the optogalvanic effect in probing the properties of CO gas laser medium
Abstract
Some new applications of the optogalvanic spectroscopy technique is proposed in the present paper. Under fixed discharge conditions, using the intracavity optogalvanic technique, the saturation parameters of the CO laser medium and its dependence on temperature and current have been measured. By measuring small-signal optogalvanic signal response, the gain distribution and the ratio of the population of vibrational levels have been obtained and the resonance self-absorption of a few lines has been observed. The method is simple and rapid, so that it may be used for real-time measurement of some dynamic parameters in a gas laser.
