Abstract
An optical fiber which includes a core region embedded within a cladding. The core region of the optical fiber further comprises multiple sections, each doped with rare earth ions.
Claims15
A fiber laser, comprising:
- a laser optical fiber comprising a first single mode core region embedded within a cladding, the first single mode core region having two non-concentric core glass sections, wherein:
- each of the core glass sections is doped with a rare-earth ion;
- each core glass section comprises a semi-cylindrical rod having a ground surface;
- and
- the ground surfaces are disposed in direct physical contact with one another such that the two core glass sections form a cylinder, such that each core glass section is in continuous contact with the other core glass section along a length of the fiber.
