| 摘 要： | 在激光惯性约束核聚变(ICF)精确打靶中,对激光束变换、整形和控制要求苛刻,通过数字在线操控技术能够在线实现激光系统的自动校准,而频率变换是数字在线操控技术中的关键一环。在不进行逼近迭代计算的情况下,基于可逆的傅里叶变换和龙格-库塔算法,对神光II终端靶场系统中负单轴晶体KDP的"I+II"类频率变换的逆问题进行了探讨和相应的算法研究,并给出了对应的模拟计算结果。最后,与神光装置运行的实验数据进行比对,验证了频率变换逆问题算法的正确性和稳定性。 |

| Abstract: | For the precise targeting in inertial confinement fusion (ICF), the requirements for beam transformation, beam shaping and beam control are harsh. The digital control of key technologies online can realize the automatic calibration of the laser system, of which frequency conversion is a crucial part. Based on the reversible algorithm of Fourier transform and Runge-Kutta method without any iterative computation, the inverse problem of type “I+II” KDP frequency conversion is studied in detail on the final optical assemble (FOA) at SG-II upgrade facility. And, some numerical calculation results are also presented. Finally, compared with experimental datas at SG-II upgrade facility, the correction of corresponding theories and the stability of algorithm are verified during the derivation. |
