Title: Waveguide laser
Inventor: MACCORMACK STUART
IPC: H01S3/094
Filed: 2000-08-01
Abstract: Embodiments of 980 nm ytterbium-doped fiber lasers illustrate features of novel high-efficiency optical lasers. In a cladding-pumped fiber laser comprising a core region (31) in optical proximity to a cladding region (32), a rare-earth dopant (35) is disposed within the cladding region in such a manner that higher levels of population inversion can be achieved and the cladding region itself is arranged to confine the pump energy such that at least one-fourth of the pump energy is absorbed while achieving optical transparency. Various dopants may be disposed within the core region and/or the cladding region to provide a desired refractive index profile, to provide a photosensitive core region in which reflective gratings (37, 38) may be written, and to dissipate unwanted emissions at longer wavelengths. A tapered fiber (21) may be used to improve the coupling efficiency between a pump energy source (10) and the optical laser.
