CFRP possesses an extremely high specific strength, and the development of cutting and joining of CFRP is expected for the increase in applications in various industrial fields. To obtain fine cuts in CFRP, high-quality disk lasers are applied to various types and kinds. It was understood that fine cuts could be produced in some CFRP with a small focused laser beam at extremely fast speed. It was also revealed that a laser direct joint between Type 304 plate (of 30 mm width and 3 mm thickness) and CFRP sheet (of 20 mm width and 2 mm thickness) possessed a shear tensile load of about 3000 N, and fracture occurred in the CFRP near the lap joint.
