Abstract
A passively mode-locking laser and corresponding method is described. The laser comprises a resonator () terminated by first () and second () mirrors and folded by a third () and fourth () mirror. The third mirror comprises a reflector () surmounted by a multilayer semiconductor gain medium () including at least one quantum well layer while the second mirror () comprises an intensity saturable mirror. The resonator is configured to provide a cross sectional area of an intra cavity resonating field on the intensity saturable mirror that is greater than or equal to a cross sectional area of the intra cavity resonating field on the multilayer semiconductor gain medium. This arrangement provides a passively mode-locking laser that exhibits increased stability when compared to those systems known in the art.
