Synthesis and Dynamic Control of Acousto‐Optic Multifocal Extended‐Depth‐of‐Focus Beams Based on the Superposition of Multi‐Chirp Signals

ABSTRACT Long depth‐of‐focus (DOF) beams maintain stable focusing over an extended axial range and are important for advanced microscopy, volumetric imaging, optical manipulation, and laser processing, particularly high‐aspect‐ratio glass micro‐hole drilling. Conventional methods...
