Application of opto-galvanic effect in probing the properties of CO gas laser medium
Some new applications of the optogalvanic spectroscopy technique is proposed in present paper. Under fixed discharge condition, using the intra-cavity optogalvanio technique, the saturation parameters of CO laser medium and its dependence on the temperature and current have been measured. By measuring small-signal optogalvanic signal responsivity, 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 obtained and the resonance self-absorption of a few lines has been, observed. The method is simple and rapid, so it may be used for real-time measnromenl of some dynamic parameters in gas laser.
