摘要
B积分判据自从建立后,一直是大型激光驱动器控制非线性效应的基本设计判据。综述了针对国家点火装置建立两个B积分判据的实验过程和模拟过程,解释了B积分判据的原理和产生条件,指出了B积分判据的适用性以及存在的问题,得出了两个B积分判据并不完善的结论。要准确地确定适用于当前大型高功率固体激光装置的B积分判据,应当综合考虑当前激光装置的实际条件,开展相应的实验和模拟。
Since the establishment of the B-integral criterion,it has been a basic design criterion for the nonlinear effect control in large laser drivers.Through an overview of the experimental and simulation processes for establishing two B-integral criteria in the national ignition facility,we explain the principle and the creation conditions of the B-integral criteria,and point out the applicability and the existing problems of the B integral criteria.It is concluded that the two B-integral criteria are imperfect.In order to accurately determine the B-integral criteria applicable to the current large high power solid-state laser devices,the actual conditions of the current laser devices should be comprehensively considered and the corresponding experiments and simulations should be conducted.
