Abstract
The beam combination method using stimulated Brillouin scattering phase conjugate mirrors is a promising technique for solid state lasers of high power/energy operating with high repetition rate. The key technology of this method is the phase control of the SBS waves. In the previous works, the principle of this phase control technique was demonstrated experimentally. As a next step, in this work, amplifiers have been added to the beam combination system. Inserting the amplifiers, a stabilized phase difference has been obtained with a fluctuation less than λ/50 at 44 mJ total output energy and 10 Hz repetition rate.
