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

Transverse mode instability power threshold in a 3.02 kW fiber oscillator has been compared in co-, counter-, and bidirectional pumping schemes and results show that the threshold is higher in the bidirectional pumping configuration.

For convenient measurements in many applications, wavelength alterations should be translated to the change in intensity of the output light. In this Letter, a novel method based on monitoring the Moiré pattern using a simple dispersive planoconvex
