Abstract
A four-arm grazing-incidence cavity (GIC) is demonstrated. It ensures stable single-mode operation in a pulsed laser system by interferometrically enhancing mode selection; the corresponding standard GIC operates on five modes. We show that the four-arm GIC gives the best overall performance in terms of mode selectivity and threshold when compared with the standard GIC or with three-arm GIC's. In addition, an analysis of the interference effect is detailed that allows the four-arm GIC to be optimized for mode selection. Threshold gain and cavity losses are calculated, and the predicted mode spacing and complex reflectance are experimentally verified.
