Abstract

We demonstrate a 60µm core diameter single-trench Yb free Er-La-Al doped fiber having 0.038 ultra-low-NA, using conventional MCVD process in conjunction with solution doping process. Numerical simulations ensure an effective single mode, the effective area varies from 1,820µm2 to 1,960µm2 for different thicknesses of trenches and resonant rings. This fiber has been fabricated with conventional fabrication process, which can dramatically reduce the fabrication cost, hence suitable for mass production. Moreover, all solid structure ensures easy cleaving and splicing. Experimental measurements demonstrate a robust effective single mode operation. Furthermore, this fiber in 4%-4% laser cavity shows a record efficiency of 46% with respect to absorbed power.
