Abstract:

Effort was expended in a fundamental study of useful or potentially useful materials in optical maser technology. Very small crystals of betaGa2O3 and powders of alpha- and beta-Ga2O3 have been prepared, a d preliminary observations of their fluorescence was made. Many solid state lasers, when operated very close to thr shold, exhibit n output which consists of a regularlyspaced series of spikes with an exponentiallydamped amplitude. The phenomenological theory of Statz and deMars predicts these effects. A comparison of the theory and experimental data is given for a three-level system ruby and a four-level system Nd3 in glass. A more exact treatment of the rate equations for the three-level system is in better accord with the experimental results for ruby. In the case of the four-level system, the observations are believed to be the first of this type for the Nd3 glass laser. The results are in qualitative agreement with the theory. Author
