A Lee hologram and Digital Micro Mirror Device (DMD) are used for modulating the laser beam to a uniform one all over its beam diameter. The efficiency and uniformity of super Gaussian beams generated through volume holographic optical component is experimentally demonstrated with optimized parameters. Super Gaussian beam generated by volume holographic grating with unique diffractive properties are advantageous for variety of laser applications. |
