研究目的
To study the precision cutting technology of LiNbO3, a brittle and difficult-to-machine material, using femtosecond laser cutting to improve cutting quality and reproducibility while reducing thermal effects and chipping.
研究成果
The study successfully achieved high-quality and reproducible cutting of LiNbO3 by optimizing femtosecond laser cutting parameters and employing two optimization methods (air cooling and water cooling). The water-cooling method provided superior results, meeting the product requirements for LiNbO3 cutting.
研究不足
The study acknowledges the challenge of reducing thermal effects and chipping in femtosecond laser cutting of LiNbO3, despite the optimization of process parameters and the use of shorter wavelengths.
