Thermal, stress, and thermo-optic effects in high average powerdouble-clad silica fiber lasers

摘要

Yb:glass fiber lasers have matured to the point where the averagenpower scaling of such devices to the kilowatt level and beyond can benrealistically pursued. In this paper, we present a comprehensive studynof thermal, stress, and average power scaling in double-clad silicanfiber lasers. We show that careful management of thermal effects innfiber lasers will determine the efficiency and success of scaling-upnefforts
