Abstract
A high power fiber laser/amplifier is comprised of a multi-mode rare-earth-doped helical core disposed within a cylindrical inner cladding. The inner cladding is enclosed within an outer cladding whereby the core effectively produces single-mode operation with a circularly polarized near-diffraction-limited beam quality output when pump radiation is injected into the inner cladding.
