Abstract

The effect of temperature variation along a high power fiber amplifier on the SBS threshold is considered theoretically. We show that for an end-pumped rare-earth doped double-clad fiber the inhomogeneous distribution of temperature, which is caused by absorption of pump radiation, may result in total suppression of SBS even for output powers well above 200 W.
