KDP晶体支撑系统工作姿态确定
Ascertainment of operating posture of KDP crystal supporting system
摘要
Abstract
With the aim to investigate optimum operating postures of the supporting system of a KDP crystal,the influence of operating posture on the gravity-induced distortion of the supporting system,as well as the deflection of the KDP crystal and the incident angle change of the laser beam due to the distortion were studied.A concept of key stiffness component was proposed to theoretically analyze the gravity-induced distortion of the supporting system on the occasion of various operating postures.Using the finite element method,the gravity-induced distortions of the supporting system with different operating postures,the induced deflection of the KDP crystal and the incident angle change of the laser beam were calculated and then compared,thus the influence of the key stiffness components were figured out.The numerical results show that under the function of the key stiffness components,the distortion of the supporting system,the deflection of the KDP crystal and the induced incident angle change vary with the operating postures,and the minimum incident angle change is 76 μrad when the supporting system operates under the optimum operating posture.Hence,the optimum result meets the requirement for ascertainment of the operating posture of KDP crystal supporting systems.关键词
