Abstract

This work presents a testing instrumentation which allows to determine important laser beam characteristics. The beam analyzer Laserscope UFF100 is moved along the laser propagation path and takes intensity profiles at several positions. With this 3D intensity data we determine the characteristics laser beam propagation parameters out of the result of a least square fit. The results show excellent agreement with the ordinary Gaussian beam propagation theory. The choose of the correct beam transforming optics, such as beam expanding telescopes or adaptive mirrors, can now easily be achieved in order to adapt the laser to its desired process.
