We derive explicit analytical relations to describe paraxial light beams that represent a particular case of the hypergeometric (HyG) laser beams [J. Opt. Soc. Am. A25, 262-270 (2008)JOAOD60740-323210.1364/JOSAA.25.000262]. Among these are modified quadratic Bessel-Gaussian beams, hollow Gaussian optical vortices, modified elegant Laguerre-Gaussian beams, and gamma-HyG beams. Using e-beam microlithography, a binary diffractive optical element capable of producing near-HyG beams is synthesized. Theory and experiment are in sufficient agreement. We experimentally demonstrate the ability to rotate dielectric microparticles using the bright diffraction ring of a HyG beam.
我们推导了明确的解析关系来描述傍轴光束，这些傍轴光束代表了超几何（HyG）激光束的一种特殊情况[《美国光学学会志》A25，262 - 270（2008年）JOAOD60740 - 323210.1364/JOSAA.25.000262]。其中包括修正二次贝塞尔 - 高斯光束、空心高斯光学涡旋、修正优美拉盖尔 - 高斯光束以及伽马 - HyG光束。利用电子束微光刻技术，合成了一种能够产生近HyG光束的二元衍射光学元件。理论与实验结果吻合良好。我们通过实验证明了利用HyG光束的明亮衍射环旋转介电微粒子的能力。
