The effect of population inversion saturation on the transverse mode instability threshold in high power fiber laser oscillators

Abstract To achieve a 3.02 kW Yb-doped fiber laser oscillator, the behavior of transverse mode instability (TMI) is experimentally studied in different pumping configurations; co, hybrid, counter, and bidirectional. A comparative analysis showed that population inversion saturation has a substantial...
