Claim Text:
1. A high-power, heat dissipating optical fiber device comprising: a section of optical fiber configured to propagate light, the section of optical fiber including an uncoated fiber segment and a coated fiber segment; a cooling chamber, substantially encapsulating the section of optical fiber; a heat-dissipating fluid within the cooling chamber having a refractive index selected to control the interaction and propagation of the light in the fluid; a fluid ingress and a fluid egress extending from a surface of the cooling chamber; and a pump for allowing fluid to flow through the cooling chamber, the pump forcing fluid into the fluid ingress and exiting the cooling chamber via the fluid egress; wherein the high-power, heat dissipating optical fiber device yields an output greater than one kilowatt of pump laser power; and wherein the fluid comprises a heat transfer coefficient of at least 100 W/m
