Abstract
 An in­ve­sti­ga­tion has been ma­de of de­pen­den­ce of mar­king con­trast on sur­fa­ce ro­ug­hness, spa­cing bet­we­en hatches (that is the pitch bet­we­en hatches) and the speed for pro­ducts ma­de of tool steel. Ex­pe­ri­ments ma­de con­cern pul­se la­ser Cu­Br uti­li­zing МО­РА system.

Keywords: laser marking, contrast, roughness.
