When measuring implements are marked by laser, two points must be studied, and they are calibration tails' precision and its quality. In this paper, what we are interested in is how to get qualified calibration tails. Calibration tails' quality is determined by three aspects: laser beam, optical system and workpiece. We conducted research into their effects on line quality with a 90 w Q-switch YAG laser marking system made by Rofin-Sinar. Laser beam has three factors that have effects on mark results: laser power (lamp current), Q-switch frequency and beam mode. Optical system refers to scanners and lens. Scanning velocity is one of the two parameters of scanners, and the other one is delay time for beam OFF. De-focus value is the parameter of focus lens. All these parameters' effects on calibration tails' quality are discussed one by one in the paper, and the author analyzed the effect of the surface condition of workpiece at last.
