Abstract:
A multi-clad optical fiber design is described in order to provide low optical loss, a high numerical aperture (NA), and high optical gain for the fundamental propagating mode, the linearly polarized (LP) 01 mode in the UV and visible portion of the optical spectrum. The optical fiber design may contain dopants in order to simultaneously increase the optical gain in the core region while avoiding additional losses during the fiber fabrication process. The optical fiber design may incorporate rare-earth dopants for efficient lasing. Additionally, the modal characteristics of the propagating modes in the optical core promote highly efficient nonlinear mixing, providing for a high beam quality (M 2 <1.5) output of the emitted light.

Claim (Index 1):
A fused silica based, multi-clad optical fiber comprising:\n a core surrounded by a first cladding layer, whereby the optical fiber has a high NA; whereby the fiber is configured to convert low beam quality visible or UV light, having an M 2 >>1.5, to high beam quality light, having an M 2 <1.5; a hydrogen dopant, whereby the fiber is configured to provide low propagation losses in the visible or UV portions of the optical spectrum; and, the core comprising a GRIN structure.
