Fiber Induced Fine Engraved Line Study of Al2O3 Ceramics by Picosecond Laser
英文摘要
We propose a new ways that machining grooves on the ceramics surface, using optical fiber induced laser beam to achieve the fine ceramic surface processing. The electric field intensity of laser through optic fiber were simulated based on the analysis of finite difference time domain. The enforcing effect of light intensity was demonstrated from both experiments and simulations, its role in inducing the beam can reach the material surface microstructure processing results. Comparison with unused optical fiber induced laser processing, light enhancement makes a fine etching on ceramic surface which have high melting point, high physical properties of hard and brittle. The enhanced regional less than the focused beam diameter (50μm) ensure the machining accuracy can be improved.
