Small core collimated single-mode continuous fiber laser can achieve more stable coupling ability, stronger penetration ability, greater penetration depth, greater aspect ratio, and smaller welding deformation in the welding of high reflective materials such as aluminum and copper for power cells, and inhibit the formation of brittle intermetallic compounds. It is suitable for precision welding of different materials.

The 976nm pump source solution launched by Xinghan laser has strong brightness, high stability and good cost performance.
