Laser power and speed of scanning are the main parameters affecting the sintering process. Further details on different types of lasers and their effects on 3D printing can be found in Lee et al. . Fine resolution and high quality of printing are the main advantages of powder bed fusion, which make it suitable for printing complex structures.
In this work, using this laser system, laser processing of several ceramics such as AlN, Al 2 O 3, YSZ was investigated. Since functional ceramics also exhibit wide-ranged properties such as thermal conductivity from 3 W·m-1 ·K-1 for YSZ to 240 W·m-1 ·K-1 for AlN, we found that the dependece of ablation volume rate on the pulse duration showed a big difference in various ceramics. We will report a fast and comprehensive survey of ultrafast laser processing of cearamics.
In fiber lasers, ultrafast pulses with a high repetition rate are widely used, such as optical communication [1,2], frequency combs [3,4], and optical sampling [].For resonators with a high repetition rate, the single pulse energy and peak power are relatively low, which can effectively avoid some nonlinear effects in the amplification process, thereby improving the overall efficiency of the ...
