Metal Foils for Use in Pulsed Laser Applications
Abstract
The metal foils under discussion are 0.002'' (50 micro m) and less in thickness. Leaving the mechanical properties for specific applications to the engineers in charge, there are at least three very important metallurgical considerations in the fabrication and use of foils of the thickness mentioned above. The first is cleanliness. There must be no inclusions in the finished foil, the size of which approximates the thickness of the foil. Such inclusion would be sure to impair the integrity of the foil-clumps of somewhat smaller ones would do the same. In addition long stringers of otherwise acceptable inclusions (0.0001" and less} will, if they occur near the surface, partially separate from the main metal and produce "blisters" and/or "slivers". long stringers even deep within the foil will impair the fabrication and ductility of the fail though the impairment may not be catastrophic.
