报道了一种高增益、低热致波前畸变的激光二极管泵浦Nd：YAG板条放大器，其有源介质尺寸为7 mm×35 mm× 138.2mm，在200 Hz、1440 W脉冲泵浦条件下，无种子光放大时，He-Ne探针通过增益介质的热致波前畸变为0.165 λ @633nm（RMS）。该放大器具有稳定的像差特性，主要有两个低阶项：离焦和0 °像散。测量了放大器的荧光分布、储能和小信号增益，与计算结果吻合较好。在泵浦重复频率为200 Hz时，采用平凹腔结构，荧光分布均匀，最大储能为3.2 J。在重复频率为200 Hz，注入偏振种子光为25 μJ，泵浦功率为1440 W时，小信号增益达到9.45。该放大器已成功地应用于200 Hz、5 J、1.7倍衍射极限输出的MOPA系统。
A high gain, low thermal-induced wavefront distortion, laser diode-pumped Nd: YAG slab amplifier is demonstrated with its active media dimensions of 7 mm×35 mm×138.2 mm. Under the 200 Hz, 1440 W pulse pumping condition while no seed light to amplify, the thermal induced wavefront aberration of a He-Ne probe passing through the gain meUdium is 0.165 λ@633 nm (RMS). The amplifier shows stable aberration character with two major low-order terms, defocus and 0◦ astigmatism. The fluorescence distribution, stored energy, and small-signal gain of the amplifier are measured and have a good agreement with the calculated results. In theamplifier, the fluorescence is uniformly distributed and the maximum stored energy of 3.2 J can be achieved with a plane-concave cavity at 200 Hz pump repetition frequency. For a repetition frequency of 200 Hz, 25 μJ injection polarized seed-light and 1440 W pump power, the small signal gain reaches 9.45. The amplifier has been successfully employed in a 200 Hz, 5 J, MOPA system with 1.7 times diffraction limited output.
