Fig. 7From: Intensity noise as a driver for transverse mode instability in fiber amplifiersTMI threshold as a function of the relative intensity noise (RIN) of the pump and the seed. The artificially imprinted noise contains frequencies from 1 Hz up to 2 kHz. The impact of the pump intensity-noise (blue dots) on the TMI threshold is significantly stronger than that of the seed intensity-noise (red dots)Back to article page
