Abstract
A fiber optic laser pumped via its cladding has a liquid component in the cladding and an index of refraction sufficient to promote total internal reflection of light carried by the cladding for pumping the laser. In one embodiment, the liquid component is provided by immersing the fiber clad with a curable polymer and a protective coating in a fluorinated organic compound.
