During the last decades laser micromachining became a valuable tool for many applications in automotive, medicine, tool construction, or mobile technology. Beside the quality, processing time and production costs are crucial questions. A promising approach to achieve high throughput combined with good processing quality represent laser ablation by an assisting magnetic-field. Therefore, we studied the influence of an applied magnetic field to the ablation behaviour of silicon by using short and ultrashort laser pulses. Based on the experimental results we report on a first theoretical model that addresses the energy distribution of the heated electrons in the irradiated area.
