| 摘要 |
The present invention concerns a method for processing an at least partially fluid-absorbent and at least in one spectral range transparent workpiece. The method is characterized by irradiating the workpiece with pulsed and focused laser radiation, wherein the spectrum of the laser radiation comprises at least one wavelength in the transparent spectral range of the workpiece, and the focus of the laser radiation is positioned on or within the workpiece. Before and/or after the irradiation, a fluid photo-sensitizer is applied onto the workpiece, this photo-sensitizer having an absorption peak at or near half a wavelength of the laser radiation. The invention also concerns a device for performing such a method.
