摘要：

Three definitions of the beam quality, characterized by waist radius and far-field divergence, of high average power laser beams are investigated. The beam parameters can be defined by their second moments, the power content profile and the power content area. The methods of measurement are described in detail and compared with respect to their suitability for two high-power laser systems: a cw Nd:YAG-rod laser and an annular system. The validity of the ABCD law was checked experimentally. Additionally, third and fourth-order intensity moments were used to characterize the laser field in more detail.
