A 330 watts YDFL with China-made DCf

摘要

A high power Ytterbium-doped fiber laser (YDFL) with China-made double clad fiber (DCF) is introduced in this paper. The Geometric parameter and laser characteristics of the newly designed fiber have been studied. When both ends of the fiber were pumped by two high-power laser diode with the total lunched power about 600W , we got the laser output of 330W, with an optical-to-optical efficiency of 55%.
