A comprehensive observation of the stimulated Brillouin scattering (SBS) phenomena in a high power nanosecond linearly polarized Yb-doped double-clad fiber amplifier is presented. According to the behavior of SBS, the amplification process is divided into four regions. All the temporal, spectral and
## Abstract The gain and the output power of an erbiumβdoped fiber amplifier (EDFA) are found to be sensitive to input power level fluctuations. Many feed back methods have been proposed to stabilize the gain of an EDFA. These feed back methods are based on sampling and detecting output light and u
