摘要

利用超短脉冲激光制备单晶CVD金刚石的三维结构。激光与金刚石晶格的相互作用导致永久的结构改变,这种改变高度局限于焦点。严重的球差损害了金刚石表面以下的制造精度。我们实现了自适应像差补偿,以确保最佳的制造性能。分析了表面和亚表面激光加工的结构改性性质。

Ultrafast laser processing of diamond
Ultrashort pulsed lasers are used to fabricate 3D structures in single crystal CVD diamond. The interaction of the laser with diamond lattice leads to a permanent structural modification, which is highly localized at the focus. Severe spherical aberrations compromise fabrication precision below the diamond surface. We implement adaptive aberration compensation to ensure optimum fabrication performance. The nature of the structural modification is analysed for both surface and subsurface laser fabrications.
