激光通道传输热效应仿真

Thermal Effect Simulation for Laser Channel Transmission

采用数值计算方法分析了高能激光在光束控制器内部传输所产生的热效应及其对激光远场光斑的影响。结果表明,对于较高激光能量,光束控制传输通道中的激光热效应不容忽视,它会明显影响光束控制系统的发射性能,降低远场目标处的激光能量集中度,并使光斑产生较严重的畸变。

The thermal effect of high-energy laser produced within the beam controller and its influence on laser far-field spot are analyzed with numerical calculation method. The results show that the thermal effect produced by the laser with a higher energy in the transmission channel for beam control cannot be ignored. It will obviously affect the transmitting property of the beam control system, reduce laser energy convergence at far-field target and cause serious distortion on spot.
