大口径片状放大器增益均匀性实验研究

Research of Gain Uniformity in Large Aperture Slab Amplifier

介绍了一台新型大口径片状放大器的实验研究以及放大器的结构组成。利用多束探针光系统测试了大口径片状放大器通光口径方向上的增益均匀性 ,不同抽运条件下的实验结果表明 ,在 2 2kV正常工作电压下 ,大口径片状放大器全口径的增益均匀性为 1 0 6∶1。

This paper presents the experimental research of a new large aperture slab amplifier. The structure of the amplifier is also introduced. With a multi-probe system, the gain uniformity over the slab clear aperture is tested. Experimental results under different pumping conditions indicate that the gain uniformity over the slab clear aperture is about 1.06:1 at the normal voltage of 22 kV.
