摘要
涡旋光的研究与应用是当前光学领域的前沿和热点.本文介绍了一种方便实用的涡旋光制备方法.我们首先利用涡旋光与高斯光的干涉,产生了叉形光栅结构.然后采用喷墨打印技术,将此叉形光栅图案打印在激光打印胶片上.最后通过平面光束照射叉形光栅,利用胶片上黑色区域的光吸收效应,实现了光线通过光栅空隙处的衍射,从而成功制备了具有不同拓扑荷数的涡旋光.与传统方法相比,我们提出的涡旋光制备方法不需要复杂的光学设备或昂贵的材料,大大降低了实验的技术门槛和经济成本,使涡旋光的制备更加普及和可行.此外,这种技术的简易性和低成本特性,使其在光学实验教学和基础科学研究中具有广泛的应用前景,尤其适合于资源有限的实验环境.
Abstract
Research and applications of vortex light are at the forefront and hot topics in the field of optics.In this paper,we introduce a convenient and practical method for preparing vortex light.Initially,we utilize the interference between vortex light and Gaussian light to generate a cross-shaped grating structure.Subsequently,employing inkjet printing technolo-gy,we print this cross-shaped grating pattern onto laser printing film.Finally,by illuminat-ing the cross-shaped grating with a plane beam,we utilize the light absorption effect of the black areas on the film to achieve diffraction of light through the grating gaps,thus success-fully preparing vortex light with different topological charges.Compared to traditional meth-ods,this method does not require complex optical equipment or expensive materials,signifi-cantly reducing the technical barriers and economic costs of experiments,thus making vortex light generation more popular and feasible.Additionally,the simplicity and low-cost nature of this technique give it a broad application prospect in optical experimental teaching and basic scientific research,especially suitable for experimental environments with limited resources.
