中文摘要:
在惯性约束聚变(ICF)激光驱动器中,片状放大器系统为装置提供超过99%的能量,是装置最重要的系统之一。大口径高通量验证实验平台(ITB)装置是我国为开展ICF研究而研制的激光装置,单束输出能量达到19.6 kJ(脉宽5 ns,中心波长1053 nm)。介绍了大口径N31钕玻璃片在ITB装置400 mm单口径片状放大器系统中应用的增益特性。实验结果表明,采用尺寸为810 mm*460 mm*40 mm、Nd~(3+)离子浓度为3.5*10~(20) cm~(-3)的N31钕玻璃片,结合装置片状放大器系统放

英文摘要:
As one of the most important elements in the inertial confinement fusion (ICF) laser device, slab amplifier provides over 99% energy. The integration-test-bed (ITB) is established for the research of ICF in China with the single-beam output energy up to 19.6 kJ (pulse width of 5 ns, center wavelength of 1053 nm). This paper studies characteristics of N31 neodymium glass in 400 mm aperture, single-segment amplifying system of ITB. The N31 glasses with size of 810 mm*460 mm*40 mm and Nd~(3+) ion concentration of 3.5*10~(20) cm~(-3) are used. Results show that combined with the optimized parameters of discharge circuit for slab amplifier and structure of pump cavity, the small signal gain coefficient reaches 5.28% cm~(-1), the gain ratio is 15:1, and the gain uniformity is 1.063∶1 (maximum/ average) within 360 mm beam diameter.
