Paper Abstract

Reflective metallic optics for high power CO2 laser are very important in industrial application of laser surface modification processes (cladding, heat treatment, etc.). Copper wirrors fabricated by diamond turning method offer a very high reflectance in the IR spectral region. Usually, metallic mirrors are coated with protective films to preserve the surface from any kind of degradation. In the development of these optics, we have produced a system for heat treatment. Such a system uses a beam integrator convex mirror that divides the CO2 beam laser in several beams with a predetermined spot size. By a concave mirror all spots are overlapped on the surface which must be treated. In this way, it is possible to obtain a uniform intensity, distribution of radiation on the irradiated surface. Using different beam integrator convex mirrors, various spot sizes at the same focal distance can be achieved.
