摘　　要：针对锥形腔高能激光计后向散射能量损失补偿问题,系统分析了均匀分布激光入射强漫反射面情况下的锥形吸收腔的后向散射问题,进而针对不同高能量激光的输出光斑形状,建立了锥形吸收腔开口处光功率密度分布和后向散射总功率的数学模型,在此基础上对测量结果进行了补偿和修正,有效改善了高能量激光能量测量准确度.Aimed to energy loss compensation problem of the conical cavity high-energy laser ener the back scattering of the conical absorption cavity was analyzed in the condition of uniform di laser incidenting on diffuse reflection surface. And, aimed to high power laser＇s output facula mathematical models of optical power density distribution at open-end of conical cavity and back gross power were established. So, the measured result was compensated and amended.
