介绍了一种激光二极管双面抽运Nd：YAG陶瓷板条激光放大器，该放大器具有增益均匀、退偏损耗小的特点。在140 mm × 40 mm × 7 mm陶瓷板上，在1064 nm波长，重复频率200 Hz，脉宽200 us，总泵浦功率1215 W时，获得了2.6 J的能量储存，光光转换效率为42.8%。平均小信号增益为5.45，在横截面中的标准偏差仅为0.09，这显示出良好的浓度均匀性。由于锯齿形结构的热梯度小，在不同位置处的平均退偏损耗为2.6%。
A diode-double-face-pumped Nd:YAG ceramic slab laser amplifier with uniform gain distribution and low depolarization loss was presented. Energy storage of 2.6 J was achieved at 1064 nm with a repetition rate of 200 Hz and a pulse width of 200 us from a 140 mm × 40 mm × 7 mm ceramic slab at a total pump power of 1215 W, corresponding to an optical-to-optical efficiency of 42.8%. An average small signal gain of 5.45 was achieved with a standard deviation of only 0.09 in the cross section, which shown good concentration uniformity. An average depolarization loss of 2.6% at different positions of the slab was obtained due to small thermal gradient of the zigzag configuration.
