摘要：
Data recording on a dental prosthesis for personal identification is proposed. Data recording was performed on a dental Au-Ag-Pd alloy with a complex surface shape by femtosecond laser processing with a surface detection function based on confocal optical detection. The processed morphology of a flat dental alloy sample was investigated over wide ranges of focus positions and laser fluences of the irradiating pulses. From the experimental results, appropriate recording conditions are discussed from the viewpoint of data recording. This is the first demonstration of two-dimensional data recording on such an object with a complex curved shape (an alloy crown).
