We demonstrate a self-pumped phase-conjugate diode-pumped Nd:YAG loop resonator. In the injected configuration a maximum phase-conjugate reflectivity of 32 is obtained. The output beam has a pulse shape of ~30 ns , which shows the self- Q -switching ability of the resonator. By use of a low-refractive-output coupler, a self-starting version was produced. The resonator operated in a stable diffraction-limited TEM(00) mode, even with severe intracavity phase aberrations. A maximum energy of 5.5 mJ (2.4% of the energy of the high-brightness stacks that was incident upon the Nd:YAG crystals) in a 20-ns single-longitudinal-mode pulse was measured.
我们展示了一种自泵浦相位共轭二极管泵浦Nd:YAG环形谐振器。在注入配置下，获得了32的最大相位共轭反射率。输出光束具有约30 ns的脉冲形状，这表明了谐振器的自调Q能力。通过使用低反射率输出耦合器，制作出了自启动版本。即使存在严重的腔内相位像差，该谐振器仍能在稳定的衍射极限TEM(00)模式下运行。在20 ns单纵模脉冲中测得的最大能量为5.5 mJ（入射到Nd:YAG晶体上的高亮度堆叠能量的2.4%）。
