| 摘 要： | 为了解决空间滤波器滤波针孔堵孔问题，提出了一种新型柱面镜空间滤波器，新型柱面镜空间滤波器由柱面镜和狭缝构成。利用线性传输理论，对高功率激光束在新型柱面镜空间滤波器中的传输特性进行了数值模拟。结果表明：新型柱面镜空间滤波器的焦斑面积比传统滤波器大，而焦斑功率密度较小；新型柱面镜空间滤波器的滤波效果与传统滤波器相同，近场均匀性也相同。因此新型柱面镜空间滤波器能够抑制空间滤波器堵孔效应，可以缩短空间滤波器系统透镜焦距，从而提高功率装置的整体性价比。由此，采用新型柱面镜空间滤波器替换传统球面镜空间滤波器具有可行性。

| Abstract: | A new cylindrical-lens spatial filter is proposed to solve the blocking pinhole problem of a spatial filter. Compared with the conventional spherical-lens spatial filter, the new filter is constituted with cylindrical lens and slit. The transmission characteristics of high power laser beam in the new cylindrical-lens spatial filter are simulated using linear transfer theory. The results show that the area of the focal spot of the new filter is bigger than that of the conventional spherical-lens spatial filter, and the power density of the focal spot is smaller, while the filtering effect and near field uniformity keep the same. The new filter can effectively inhibit the blocking effect of the filtering pinhole. At the same time, the new filter can also improve the overall price of the laser device by shortening the focal length of lens. The new cylindrical-lens spatial filter to replace the conventional spherical-lens spatial filter is feasible. |
