摘要：
A measuring device based on a rotating pinhole method was designed and developed at IF-FM far recording the spatial structure of high power cw CO2 laser beams in the near and far field region. The main performance parameters of the device are presented together with the measurement results concerning the beam propagation characteristics of the 1.2 kW technological laser.
