摘要

广义高斯激光束可以被描述为众所周知的厄米-高斯(HG)和拉盖尔-高斯(LG)激光束之间的连续跃迁。从投影仪上拆下液晶显示器,制成空间光调制器。自制的SLM,用计算机生成的全息图编码,然后被用来将一个基本高斯光束从一个小框架氦氖(HeNe)激光转换成几个不同阶的广义高斯(GG)光束。实验生成的GG光束轮廓与理论预期的轮廓相符。

Generation of Generalized-Gauss Laser Beams via a Spatial Light Modulator
Generalized-Gauss laser beams can be described as a continuous transition between the well-known Hermite-Gauss (HG) and Laguerre-Gauss (LG) laser beams. A spatial light modulator (SLM) was made by removing the liquid crystal display (LCD) from an overhead projector. The homemade SLM, encoded with a computer-generated hologram, was then used to convert a fundamental Gaussian beam from a small frame Helium-Neon (HeNe) laser into several different orders of Generalized-Gauss (GG) beams. The experimentally generated GG beam profiles matched the theoretically expected profiles.
