摘要
利用单个偏振器件把一束线偏振的高斯光束分解为两束振动方向相互垂直、相互之间错开适当距离的非相干光束,这两光束以强度相加形式叠加在一起,从而形成一个一维光强均匀区域。
A simple polarizing device,by which a one-dimensional uniformlied intensity area can be producedfrom a line-polarized Gaussian laser beam,is described.The uniformlied area obtained by this technique is muchbigger than that of the former Gaussian beam. The non-uniformity Of the output beam varies from the thickness ofthe polarizing device.
