Using a complex filter for uniform distribution of Gaussan beam

激光束的光强分布为高斯分布。在激光应用的许多领域，要求光束的光强为均匀分布。本文提出了一种利用复滤波器实现高斯光束均匀化的新方法。给出了复滤波器的制作方法和实验结果。实验表明，该方法是一种能量转化率较高、容易实现、均匀化程度较为理想的高斯光束均匀化的方法。

Laser light intensity is of Gaussian distribution.It is quite important to convert it into u-niform distribution in some applied fields of laser,A complex filter for uniform distribution of laser in-tensity is designed.The method for generating this filter and experimental results are shown in the pa-per.The experiment shows that this method is one of homogenizing Gaussian beam with high energytramsform,easy realization and ideal homogeneity.
