| Outline of Final Research Achievements |
In this study, we have developed the two-wavelength laser microwelding system using femtosecond laser system and continuous wave laser system which has a wavelength of linear absorption about materials to be joined. The microwelding system is capable of joining a large area at high speed and high quality. Also, in order to understand the interaction of the femtosecond laser pulses and continuous beam during laser microprocessing, the light absorption of the femtosecond laser pulses was measured. Based on the measurement result about light absorption, we analyzed the heat transfer in the transparent material using the finite element method.
