Abstract

The beam combination technique using stimulated Brillouin scattering (SBS) phase conjugate mirrors (PCMs) proposed by one of the authors, H. J. Kong, is a promising one for realization of high energy/power laser system with high repetition rate. However, phase controlling of the SBS waves is essentially required for beam combination system, since the SBS-PCM generates the random phase. Recently, we have achieved successful results for phase locking by the self-generated density modulation method. But it showed a long-term phase fluctuation due to the long-term fluctuation of the density of the liquid SBS medium. To compensate this long-term phase fluctuation, we have designed new phase stabilization system. In this paper, we will introduce this system and show successful experimental results.
