Laser beam shaping is the process of modifying the spatial distribution of a laser beam's intensity. This is done to achieve a desired profile, such as a uniform intensity across a surface or a specific geometric shape. Techniques for shaping include using optical elements like lenses and diffractive optics, which can transform the beam's characteristics for various applications. Shaped laser beams are used in fields like material processing, medical treatments, and communications. For instance, in laser cutting, a uniform beam can improve precision and efficiency, while in ophthalmology, specific beam shapes can enhance treatment outcomes for patients.
