Abstract
A microlaser system, including a microlaser, having an elongated generally cylindrical substrate, a thin dopant film encircling at least a portion of the substrate, and a pumping laser positioned to shine onto the thin film. The thin film is between about 2 and about 10 microns thick. When the pumping laser shines on the thin film, the thin film lases in whispering gallery mode. The dopant is preferably selected from the group including transition metals and rare-earth elements. In a most preferred embodiment, the thin film is titanium-doped amorphous aluminum nitride.
