Laser Beam Homogenizer Using Multifocal Liquid Crystal Microlens Arrays

A laser beam homogenizer is developed using a tunable multifocal liquid crystal microlens array (TMLCMA). This proposed TMLCMA enables functioning at monofocal convex, multifocal convex, and multifocal concave modes. It successfully mitigates the lattice effect of beam homogenization by conventional microlens arrays and expands beam with a flat-top intensity profile.
