在技术集成实验线（TIL）原型激光设备研制的基础上，采用理论模拟指导实验和实验结果校核的方法，对影响大口径高强度惯性约束聚变（ICF）激光设备三次谐波产生（THG）效率的因素进行了详细分析和研究。此外，在2004-2005年，在一束合格性实验中充分讨论了THG系统对TIL驱动器的输出能力。实验结果表明，当基光平均驱动辐照度I1ω为2.7GW/cm2时，THG效率的实测值为50-55%，理论值为60%，表明实验结果与理论值吻合较好。
Based on the study and manufacture of the technical integration experiment line (TIL) prototype laser facility, and using the method that theoretical simulations guide experiments and experimental results check programs, the factors affecting third harmonic generation (THG) efficiency for a large-aperture, high-intensity inertial confinement fusion (ICF) laser facility have been analyzed and studied in detail. Furthermore, in the year 2004–2005, the output ability of a THG system for a TIL driver has been discussed adequately in a first beam eligibility experiment. As shown by experimental results, when the average drive irradiance of fundamental light, I1ω, is 2.7GW/cm2, the measured value of THG efficiency is 50–55% and the theoretical value is 60%, which indicates that the experimental result agrees well with the theoretical value.
