This document has been declared Stabilized and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.Ultraviolet (UV) laser marking for aerospace wire and cable is now a well established and accepted process. The purpose of this report is to provide general information on the technical basis of marking systems that apply UV laser energy to the wire surface. This includes materials for UV laser marking; the key characteristics of UV lasers suitable for this application, in terms of the mark process requirements and operational requirements; the various types of UV lasers which meet the general requirements for wire marking; and the generic components of UV laser marking systems. Subjects beyond the scope of this report include other wire marking systems not utilizing UV lasers; legibility; and contrast measurement. The contents of this document are for information only. It is not intended that it should be used as the basis for marking process specifications or standards, which are covered by SAE AS 5469 Wire and Cable Marking Process, UV Laser.
