Optics Express, 2010•opg.optica.orgThe results of theoretical and experimental studies of active tapered double-clad fibers,
intending the optimization of its imperative parameters-tapering ratio, longitudinal profile,
core/cladding diameters ratio, are presented. Using a refined taper geometry we have
demonstrated power scaling of a ytterbium fiber laser pumped by low-brightness, cost-
effective laser diodes up to 750 W, with 80% efficiency.
