Self-pumped phase conjugation in infrared-sensitive photorefractive rhodium-doped barium titanate (Rh:BaTiO(3)) is investigated with a kilohertz-repetition-rate, diode-pumped Nd:YAG laser. We also demonstrate the operation of a diode-pumped Nd:YAG master-oscillator power-amplifier system with such a compact and solid-state phase-conjugate mirror for wave-front restoration. We obtain near-diffraction-limited output pulses of 20-mJ energy at a repetition rate of 200 Hz and a 1-min response time of the phase-conjugate mirror. The performances of the Rh:BaTiO(3) crystal are compared with those obtained with a conventional Brillouin mirror.
钇铝石榴石激光器，对红外敏感的光折变掺铑钛酸钡（Rh:BaTiO₃）中的自泵浦相位共轭进行了研究。我们还演示了一种二极管泵浦钕：钇铝石榴石主振荡功率放大器系统的运行情况，该系统带有这样一个紧凑的固态相位共轭镜用于波前恢复。我们在200 Hz的重复频率下获得了能量为20 mJ且接近衍射极限的输出脉冲，以及相位共轭镜1分钟的响应时间。将Rh:BaTiO₃晶体的性能与使用传统布里渊镜所获得的性能进行了比较。
