Impact of Stimulated Raman Scattering on the Transverse Mode Instability Threshold

Impact of Stimulated Raman Scattering on the Transverse Mode Instability Threshold

Quantum defect originating from the stimulated Raman scattering (SRS) effect is a heat source that induces refractive index grating and, thus, significantly decreases the threshold of transverse mode instability (TMI), which is the main limiting factor for the power scaling of high-power fiber laser...
