    Abstract

    Amplification of high-power Stokes beam in the time serial laser beam combination by stimulated Brillouin scattering (SBS) is studied. The variation of energy extraction efficiency of Stokes beam amplification with the power density ratio of Stokes beam to pump beam is studied experimentally. The results show that energy can be extracted from pump beam when power density of Stokes beam is more than that of pump beam. The more power density of Stokes beam, more energy are extracted from pump beam. There exists a maximum for the amplification of high-power Stokes beam which is restricted by the energy of pump beam, the absorption coefficient of medium and the length of medium cell, etc. The maximum of Stokes beam amplification can be increased and the higher energy extraction efficiency can be gained through optimizing the absorption coefficient of medium and the cell length.
