摘　　要：系统提出了He Ar Xe核泵浦激光本征效率的理论模型,建立了本征效率与泵浦腔内介质温度(能量沉积)、气体总压力、He和Ar分压、Xe的含量之间的函数关系,完善了核泵浦激光腔内能量沉积模拟计算软件。研究表明:腔内气体组成决定激光效率,中子屏蔽效应对腔内能量沉积影响严重,只有当腔厚度与气体压力为一定关系时,能量沉积达最大。这为进一步的实验设计提供了理论依据。The nuclear reactor pumped lasing model (NRPLM) is proposed in the present work. The power efficiency is built as a function of gas temperature (energy deposition), cell pressure, xenon concentration, He and Ar fractions. The software for calculation of energy deposition in laser cell is improved. The results show that gas components in cell decide the laser efficiency, neutron selfshielding effect affects the energy deposition in cell. Only when the cell thickness and gas pressure are a special function, the energy deposition in cell reaches its maximum. The present work will benefit the future experimental designs.
