中文摘要：
提出了一种可以满足大能量高峰值功率受激布里渊散射（SBS）相位共轭镜要求的独立双池结构，这种结构用在双程激光放大光路中可以补偿单程放大光路产生的动态和静态相位畸变．在7．1J的入射能量下，最终得到了大于13J的能量输出．相位共轭镜的能量反射率大于65％，相位共轭保真度达到90％，并且比较了以O°平面反射镜和以SBS相位共轭镜为腔镜的双程激光放大的输出结果，结果表明使用了SBS相位共轭镜之后，即使在大能量抽运的条件下也能得到很好的近场和远场保真度．
英文摘要：
A novel dual-cell Brillouin oscillator-amplifier phase conjugate mirror for high energy and high peak power operation in double-pass solid state laser amplifier is described. Correction of static aberration and dynamic aberration induced in single-pass amplifier was achieved in the second passage through the aberrating medium under the condition of using the stimtdated Brillouin scattering phase conjugate mirror as reflector. Output energy of 13 J was obtained with input energy of 7.1 J. An energy reflectivity of 65% and a conjugation fidelity of 90% were achieved by the use of this dual-cell phase conjugate mirror. Finally, the performance of this kind of SBS reflector in a double-pass amplifier has been compared to that of a fiat mirror. The results show that the SBS reflector is highly effective in correcting the spatial aberrations of laser radiation. Excellent near-and far-field conjugation fidelities were obtained even with high input energy.
