中文摘要:
大口径高通量验证实验平台(以下简称ITB装置)是我国为开展惯性约束聚变(ICF)研究而研制的激光装置,单束输出能量达到了19.6 kj(基频发射波长为1053 nm,脉宽为5 nS)。对大口径N31钕玻璃片在ITB装置400 mm*400 mm单口径片状放大器系统上应用的热特性进行了实验研究,结果表明:在增益系数为cm~(-1)高增益情况下,整个激光链路热致动态波前畸变峰谷值d_(PV)约为5.3 lambda,处于变形镜校正范围之内;结合合理设计冷却方案,剩余波前畸变恢复时间约为2.5 h,满足了系统运

英文摘要:
The integration-test-bed (ITB) device is established for research on inertial confinement fusion(ICF) in China. The single-beam output energy reaches 19.6 kJ successfully when the fundamental frequency emission wavelength is 1053 nm and the pulsewidth is 5 ns. Experimental results of thermal effect of 400 mm* 400 mm aperture slab amplifiers in ITB devices show that the peak-to-valley value d_(PV) of pump-induced wave-distortion of the whole laser chain is about 5.3 lambda, in the revise extension of deformable mirror, when the gain coefficient is 5.28% cm~(-1). Combined with the optimizations of heat management, the thermal recovery time is about 2.5 h, which can satisfy the requirement of 4 h/shot.
