Dynamic modal characteristics of transverse mode instabilities in ytterbium-doped fiber laser oscillator

Dynamic modal characteristics of transverse mode instabilities in ytterbium-doped fiber laser oscillator

In recent years, transverse mode instability (TMI) has been widely observed in fiber laser amplifier systems. The transverse mode instability phenomenon in fiber laser oscillators is less studied. Here, we focus on the dynamical output properties, i.e., its temporal signal and modal characteristics...
