Abstract

Recently, ETCA has bought an industrial high power CO₂ laser of 22 kW from United Technologies Industrial Lasers. Before its use in material processing, a beam characterisation is necessary. We describe the set-up used to measure the power level and its fluctuations, the beam intensity profile at the near field and the far field and the polarization state of the beam. After a brief description of the laser, some measurement results are given.
