Abstract

PURPOSE:To flatly grow a solid/liquid boundary and to obtain a crystal free from a core by respectively specifying x, y of single crystal having a garnet structure represented by a chemical composition formula of Gd3-xErxGa5-y-zAlyCrzO12 so as to be in specific composition ranges. CONSTITUTION:In a single crystal represented by Gd3Ga5-yAlyO12, its optical absorption loss becomes 1/2 of the case that it does not contain aluminum in case of y>=0.05, and its deterioration scarcely occurs even with an exciting light. This effect is similar in case that Er of active element is contained, a crack easily occur at the time of growing the crystal or machining in case of y>2.5, and there is a problem in fact from the point of optical uniformity. Accordingly, the composition ratio of aluminum is preferably 0.05<=y<=2.5. As to the composition content (x) of the active element Er, in case of x>2, a crystal of high quality is not obtained. In case of x<0.03, the output as the Er laser cannot be stably produced. Accordingly, the valid range of the composition content (x) of the Er is 0.03<=x<=2.
