Beam shaping is a research area in the field of optics and photonics that focuses on designing and manipulating the shape of laser beams. This can involve changing the intensity distribution, polarization, and phase profile of the beam in order to control its properties and optimize its performance for specific applications. Beam shaping techniques are used in a wide range of applications, including laser materials processing, biomedical imaging, and telecommunications, to improve the precision, efficiency, and quality of laser-based processes.
