Abstract
A doped substrate having a substrate comprising at least one of a glass material, a single crystal material, a poly-crystalline material, a ceramic material, or a semiconductor material. The doped substrate includes a dopant comprising one or more transition metals, one or more rare earth elements, or a combination of both, the doped substrate characterized in that a spectral laser output of the doped substrate exhibits a nominally single frequency having a linewidth less than about 5 nm.
