    摘要: A composite laser gain medium is comprised of a first rare-earth element doped core; and a second rare-earth element doped cladding, at least partially, adjacent to the core. A portion of the lasing by the cladding at one wavelength within the composite laser gain medium is absorbed by the core so as to cause lasing of the core at a different wavelength. At least two distinct rare earth element pairs may be used in embodiments: (1) thulium (Tm) as a cladding rare-earth dopant and holmium (Ho) as the core rare-earth dopant; and (2) ytterbium (Yb) as a cladding rare-earth dopant and erbium (Er) as the core rare-earth dopant. Other rare earth element pairs are also believed possible. The laser composite gain medium may be configured to have a slab, or a cylindrical geometry.
