We theoretically study the influence of ytterbium (Yb)-doped fiber parameters on the transverse mode instability (TMI) in aspects of TMI threshold power, average, and total thermal loads. To understand the individual contribution of heat sources, such as photodarkening (PD) and quantum defect (QD),...
