| Abstract Scope |
In the last few years, demand for laser cleaning technology has significantly increased. Laser cleaning is the process by which contaminant are removed from a material surface by using a highly energetic focalised laser beam. Typical application of laser cleaning are paint and coating stripping, mold cleaning and rust removal. As many industrial applications required a short processing time, it is therefore a necessity to make laser cleaning process as efficient as possible. In this paper, we compared the performance of two types of fiber laser source for laser cleaning: single-mode and multi-mode. As these two types of lasers offers specific characteristics, we performed an empirical study to compare their performances in terms of cleaning speed for rust, paint and mill scale. Emphasis is put into the optimization of the optical parameters that maximize the cleaning speed with minimal substrate damage. Advantages and limitations of each system are also discussed. |
