A master oscillator power amplifier system comprising a cw Nd:YAG master oscillator, a quasi-cw diode-pumped power amplifier, and a fiber-based stimulated Brillouin scattering phase-conjugate mirror is reported. A 12-pass amplifier configuration is employed to achieve high gain in a small-length slab amplifier. Residual and pump-induced optical inhomogeneities in the slab are corrected by the fiber phase conjugator to achieve diffraction-limited output beam quality. 300 W quasi-cw output and a maximal attainable gain of approximately 150 for the system are obtained.
报道了一种主振荡功率放大器系统，该系统包括一个连续波Nd:YAG主振荡器、一个准连续波二极管泵浦功率放大器和一个基于光纤的受激布里渊散射相位共轭镜。采用12通放大器配置，以在小长度片状放大器中实现高增益。片状放大器中的残余和泵浦诱导光学不均匀性通过光纤相位共轭器进行校正，以实现衍射极限输出光束质量。该系统获得了300 W的准连续波输出和约150的最大可实现增益。
