ABSTRACT

Laser beam shaping is used in many fields of scientific, engineering, and industrial research and development and has become important for laser-based applications, such as lithography, materials processing, isotope separation, medical and illumination applications, laser printing, optical data storage, spectroscopy, photography, laser fusion, and laboratory research. These applications use a variety of the unique properties of lasers, such as high intensity, coherent, and monochromatic light of lasers. In this chapter, we shall discuss a wide spectrum of geometrical methods that have been used to shape a laser beam profile, which involves application of geometrical optics to solve the optical design problem for the laser beam shaping system.
