摘要
为解决核物理工程、表面热处理、激光加工、激光通信中传输激光束的均匀性问题,提出采用三角楔柱透镜改善线激光均匀性的新方法,并在ZEMAX开发环境下建立了整形光路系统的理论模型。利用所建立的模型,分析了整形柱透镜在不同半径、斜面夹角、透镜介质折射率等参数下光束的均匀性。研究表明:在远场条件下,通过改变整形柱透镜的参数,能够得到能量分布均匀的线激光。在实际应用中,可以采用1个半圆柱和2个相同三角楔胶合成型的简单工艺。进一步模拟发现,两种整形系统所得到的均匀度和线宽一致。
A new method using a cylindrical lens with two wedges to improve the uniformity of the line laser is provided to solve the problem of laser beam uniformly transmitting in the laser communication. The theory model of the optical system for the beam shaping ;teas built with ZEMAX. The uniformity of the beam through the cylindrical lens is analyzed with the model at the different parameters （radius, angle between two slopes and the refractive index of lens medium）. The result shows that the line laser with the uniform intensity distribution can be obtained by changing the cylindrical lens parameters under the condition of far field.
