Energy Loss Compensation of Backscattering of the High-Energy Laser Energy Meter
高能激光计后向散射能量损失补偿方法研究

Aimed to energy loss compensation problem of the conical cavity high-energy laser energy meter,the back scattering of the conical absorption cavity was analyzed in the condition of uniform distribution laser incidenting on diffuse reflection surface.And,aimed to high power laser′s output facula shape,the mathematical models of optical power density distribution at open-end of conical cavity and back scattering gross power were established.So,the measured result was compensated and amended.
