The invention relates to a component made from aluminium material with a partial or complete coating of the surfaces for brazing and method for production of the coating. An embodiment includes a rotational stimuli applied to the rotational motion for testing that includes two separate components, a bias component and a probe component. The second cylindrical portion has a second outer surface of a second diameter smaller than the first diameter. A problematic database object is identified using the performance data for the plurality of database objects, wherein the problematic database object is related to the performance problem. Differential loss is applied to both single-pass configurations appropriate for pulsed amplification and laser oscillator configurations applied to high average power cw source generation. The polymer composition according to the invention can be marked with laser light of wavelength 1064 nm.
