Recent Developments in Adaptive Optics for Laser Beam Shaping

Abstract

Judy Denise*

Adaptive Optics (AO) has emerged as a critical technology for laser beam shaping, enabling precise control over the spatial and temporal characteristics of laser beams. This paper reviews recent developments in AO systems tailored for laser beam shaping applications. We discuss advancements in wavefront sensing techniques, including Shack-Hartmann sensors, pyramid wavefront sensors, and phase retrieval methods, which enable accurate measurement of aberrations in the laser beam. Moreover, we explore novel deformable mirror designs and control algorithms that facilitate real-time correction of aberrations, allowing for efficient beam shaping with high fidelity. Additionally, we highlight applications of AOenabled laser beam shaping in fields such as laser materials processing, laser communication, and biomedical imaging. Finally, we discuss future directions and challenges in the field, including the integration of machine learning algorithms for adaptive optics control and the development of compact, low-cost AO systems for widespread adoption.
