Laser beam shaping

By Josef Hantl


Thesis describes shortly types of waves and beams. Gaussian beam properties and parameters are described in more details, Gaussian beam is the most used in atmospheric optical links. The main goal of work is studying of possibilities of laser beam shaping, mainly the beam Top hat. In this project reasons why is suitable to shape laser beam for optical communications and the most used methods for shaping of laser beam are described. The suggested processes of beams shaping are experimentally verified and properties of beams shaped of single methods are compared with each other
