Abstract

This paper presents the results of research and fabrication of a colour laser marking device on metal surfaces using a high-power fiber laser with a MOPA (Master oscillator power amplifier) configuration by intergrating semi-finished modules. Using our manufactured colour laser marking device, the effects of laser parameters such as laser power, laser pulse repetition frequency, beam scanning speed, line width on forming colour process have been researched and evaluated explicitly to provide the optimal set of parameters for the colours on each specific stainless steel and titanium metal.
