Paper Abstract

A novel Yb3+-doped double-clad silica fiber with rectangular inner cladding was designed and developed using MCVD process, solution-doping and optical machining altogether. The dimension of inner classing is 100(Mu) mx70micrometers , and Yb3+-doped concentration in the core is about 0.24wt%. The operation of the fiber laser pumped by inner cladding is reported. The threshold of laser is 34mW. When the pump power launched is 141mW, the laser output is 84mW at the wavelength and 1075.6nm, and slope efficiency is 77%.
