Thermal lens effects in an Er3+:YAG laser with crystalline fiber geometry

Article

Abstract

A resonantly diode-pumped high-power continuous-wave Er3+:YAG laser with a crystalline fiber geometry based on total-internal-reflection pump guiding is reported. Up to 9.4 W of output power could be generated and a slope efficiency of 46.8% was achieved. Intrinsic efficiencies reached up to 48.8% and an optimum outcoupling of ∼20% was found. A strong thermal lens was observed and cavity stability and hysteresis effects were studied.
