Abstract: A laser gain medium and laser system include a host material, a plurality of quantum dots dispersed throughout the host material, and a plurality of laser active ions surrounding each of the quantum dots. The laser active ions are disposed in close proximity to the quantum dots such that energy absorbed by the quantum dots is transferred to the ions, thereby exciting the ions to produce laser output. In an illustrative embodiment, each quantum dot is surrounded by an external shell doped with the laser active ions.
