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 (110) comprising a plurality of a first type of ions, e.g. ytterbium, that absorb energy at a first wavelength and transfer the absorbed energy to a plurality of a second type of ions, e.g. erbium, that lase at a second wavelength after receiving the transferred energy. A cladding region (108a,108b) 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.

Abstract: A laser (10) includes a pump source (12) that provides pump energy at a first wavelength and a laser cavity (14). The laser cavity includes a laser gain medium (16) that receives the pump energy from the pump source and creates gain at a second wavelength different from the first wavelength, and a mode stripping portion (18) coupled to the laser gain medium. The mode stripping portion causes the laser cavity to have a low Fresnel number so as to allow only the lowest-order fiber mode to resonate in the laser cavity. Higher-order fiber modes are discriminated against so as to generate a laser output (22) having a substantially diffraction limited beam in a single transverse mode at the second wavelength.
