Abstract
Using a stable-unstable resonator, formed by cylindrical mirrors, a homogeneous, rectangular intensity distribution can be generated directly by a high power CO2 -laser oscillator. Such a beam shape is especially well suited for wide area heat treatment applications. The advantages of such a resonator and the focussing properties of the resulting beam will be discussed in detail. Examples of applications, demonstrating these advantages will be given.
