Aberrations induced by high brightness lasers

The development of high brightness lasers was pushed enormously in the last five years. Two different trends can be noticed. Beside the continuous growing laser power in the multi mode sector up to 100 kW, diffraction limited laser systems are available in the range up to 10 kW [1]. High power diffraction limited lasers deliver a new quantity of laser power induced aberrations [2]. Currently no online measurement equipment for optical aberrations is available. This paper describes an alternative online method to capture the optical aberrations of lenses. The developed tool allows a comparing benchmark of different optical components.
