In this work, we study the precision cutting technology of LiNbO 3 which is belonged to brittle materials and difficult to machine. By using a femtosecond laser, we explore the influence of wavelengths on the cutting quality, the surface and cross-section morphology of the specimens were examined by optical microscopy and white light interferometer, the size of the slit width and cutting chipping, roughness have been measured. Subsequently, two optimization processing solutions have been designed to cut LiNbO 3 with high quality and high reproducibility, the thermal effect and chipping have been reduced obviously. At last, the complete cut through the plate of LiNbO 3 has been achieved. [ABSTRACT FROM AUTHOR]
