Brillouin amplification of strong Stokes seed, which can achieve the output energy of 400 mJ and amplified efficiency of about 85% under the condition that the energy of Stokes beam and pump beam is in the ratio of 39.5/1, is reported. The relationship between output energy of strong signal Brillouin amplification and the energy of Stokes beam as well as pump beam, the interaction length, absorption coefficient is investigated. The design of strong signal Brillouin amplification system with high output energy is also provided.
