演示了采用 Nd:YVO4 innoslab 激光器作为主振荡器的高功率 Nd:YAG 端泵浦板条放大器链。通过第一级双通、第二级单通，实现了5210W的链输出功率和4倍衍射极限的光束质量，工作频率为1kHz，脉冲宽度为200μs，光学效率为29%。
A high power Nd:YAG end-pumped slab amplifier chain with a Nd:YVO4 innoslab laser as the master oscillator is demonstrated. A chain output power of 5210 W with beam quality of 4 times the diffraction limit is achieved by double-passing the first amplifier stage and single-passing the second stage with an optical efficiency of 29% while working at a frequency of 1 kHz and pulse width of 200 μs.
