Abstract

The paper presents an experimental study of the application of thin holograms with increased (due to the use of a triangular pattern profile) diffraction efficiency for the formation of light beams with non-zero orbital moments (phase vortices). It is shown that in this case efficiency can be increased substantially (in theory — up to 100%). Transformation is done without any distortion of the formed beam.

非对称全息图相涡的形成

本文通过实验研究了薄全息图在非零轨道矩(相位涡流)光束形成中的应用，提高了衍射效率(由于使用三角形图案轮廓)。结果表明，在这种情况下，效率可以大大提高(理论上-高达100%)。变换后的梁不会产生任何变形。
