Abstract. Laser engraving process is widely used for various industrial applications, such as the creation of small and complex geometries with ultra-high precision. As surface topography can affect the functionality of produced surfaces in various ways, it is required to carry out comprehensive experimental work in order to correlate the laser engraving process parameters with surface topography characteristics. In the current paper, the surface topography of SAE304 stainless steel specimens in respect to laser power, scanning speed and pulse repetition rate is studied through microscope observations. The findings indicate that the scanning speed is the most dominant parameter regarding surface roughness and from the viewpoint of surface quality, it is suggested that higher scanning speed, lower power and pulse repetition rate values should be employed.
