Fig. 6From: 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. The artificial pump intensity-noise contains frequencies from 1 Hz up to 2 kHz. For a value of 2.9% the pump-RIN decreases the TMI threshold by 63% from its intrinsic value (95 W vs. 257 W)Back to article page
