Abstract

The research teams at ETCA have designed and developed more than a dozen transportable analyzers used to characterize high power CO₂ laser beams at 10.6 µm and providing a real time high rate space-time distribution of the beam at all points on a cross-section. For example, in a range of analyzers covering analysis fields up to 200 x 200 mm2, we have developed equipment providing the following performance levels: for a field of 20 x 20 mm2, resolution of 0.4 mm on 50 lines, 50 images per second, and for a field of 5 x 5 mm2, resolution of 50 µm on 100 lines, 5 to 25 images per second, and permissible power of 10 kW/mm2 for another.
