Abstract:

Enhancement of the coefficient, X2, of optical second harmonic generation by resonant absorption is discussed. In particular the conditions under which the resulting increase in X2 overcomes any losses due to the linear absorptions so introduced are developed. Trivalent rare earth dopants in crystalline hosts of suitable symmetry, among other feasible materials, are examples of materials shown capable of efficient harmonic generation. Experimental techniques are developed for use in measuring and testing the relevant material properties, among them the use of stimulated Raman effect methods for shifting the frequencies of available laser sources. The theory of harmonic generation in absorbing materials is discussed plus the variation in measurement techniques required in experimental studies of these materials. Author
