Abstract
An optical device, a method of making a laser gain medium, and a method of suppressing parasitics in a laser device include a core region comprising a plurality of a first type of ions that absorb energy at a first wavelength and transfer the absorbed energy to a plurality of a second type of ions that lase at a second wavelength after receiving the transferred energy. A cladding region coupled to the core region comprising another plurality of the second type of ions that suppress parasitics in the optical device by absorbing energy of at least a transverse portion of the second wavelength that enters the cladding region.
