Abstract:
A resonator mirror with a saturable absorber for use in a solid-state laser resonator, said laser resonator having an output power greater than 1W and being adapted for a laser radiation having wavelength &lgr;L comprising:a substrate on which a series of layers of a plurality of semiconductor layers is formed; said series of layers including a Bragg reflector formed of a plurality of alternately arranged layers comprising a first material with an index of refraction nH and a second material with a lower index of refraction nL compared with the latter grown on a surface of the substrate; and a threefold layer being grown directly on the Bragg reflector, wherein a single quantum layer is embedded within two layers of the first material or within two layers of the second material and outside an intensity minimum for the laser radiation within said laser resonator and said threefold layer has a combined optical thickness that is a whole-number multiple i of Î»L2wherein an anti-reflection coating is applied to the threefold layer and is designed for the laser wavelength &lgr;L.
