Keywords:laser

High nonlinearity represented by stimulated Raman scattering and self phase modulation is fiber lasers biggest drawback at high power operation. Due to the high power operation of ultra short pulse laser, this study "Divided Pulse Amplification" overcome the nonlinearity. We demonstrated binding pulse and optimize the 1030nm fiber amplifier.
