  • Title: Thermo-optical effects in high-power ytterbium-doped fiber amplifiers.
    Author: Hansen KR, Alkeskjold TT, Broeng J, Lægsgaard J.
    Journal: Opt Express; 2011 Nov 21; 19(24):23965-80. PubMed ID: 22109421.
    Abstract:
    We investigate the effect of temperature gradients in high-power Yb-doped fiber amplifiers by a numerical beam propagation model, which takes thermal effects into account in a self-consistent way. The thermally induced change in the refractive index of the fiber leads to a thermal lensing effect, which decreases the effective mode area. Furthermore, it is demonstrated that the thermal lensing effect may lead to effective multi-mode behavior, even in single-mode designs, which could possibly lead to degradation of the output beam quality.
