Abstract
A laser with a spectral converter. The novel laser includes a spectral converter adapted to absorb electromagnetic energy in a first frequency band and re-emit energy in a second frequency band, and a laser gain medium adapted to absorb the re-emitted energy and output laser energy. The spectral converter includes a plurality of quantum dots having an emission spectrum matching an absorption spectrum of the gain medium. In an illustrative embodiment, the spectral converter is adapted to convert broadband energy to narrowband energy, and the gain medium is a REI-doped solid-state laser gain medium.
