Paper Abstract

We report the alignment details for efficient direct coupling of a single-mode Nd fiber laser to a multimode, highly divergent laser diode pump source. A double-clad fiber structure with a rectangular shape and large NA (0.4) allows for efficient excitation of the single-mode core in a simple end-pumped configuration. Pump conversion efficiency of up to 25% is observed, with CW output power to 0.12 Watt in the case of a single laser diode pump.
