Paper Abstract

This paper presents magnetic-field-assisted femtosecond laser drilling of bone with deep drilling depth, good surface quality and high removal rate. In this study, the feasibility of producing deep cavity under magnetic field condition is investigated. When magnetic field is introduced, the depth of drilling hole is increased from 236μm to 483μm, and the removal rate is increased from 3.04×10-3 mm3/s to 5.46×10-3 mm3/s. Moreover, no thermal damage including carbonization is observed during laser drilling process.
