The utility model relates to an optical device laser welding hangs down stress structure, include and is placed on the weldment by the weldment by weldment and weldment that by marginal perpendicular with the weldment top surface to the side of the weldment, be equipped with sunk structure or protruded structure by bottom to the side of the weldment, the incidence point of oblique fire laser is located sunk structure or protruded structure's lower part and have the certain distance with the weldment. This structure can make and is close the same by the fusion penetration of weldment and weldment, and it is unanimous that the optical device stress of production is even, welding stress obtains fine release, the spot size is welded to the outward appearance. 本实用新型涉及种光器件激光焊接低应力结构，包括被焊件和焊件，被焊件放置在焊件上，被焊件侧面边缘与焊件顶面垂直，被焊件侧面底部设有凹陷结构或者突出结构，斜射激光的入射点位于凹陷结构或者突出结构的下部并且与焊件存在定距离。该结构能够使被焊件和焊件的熔深接近相同，生产的光器件应力均匀、焊接应力得到很好的释放、外观焊斑大小致。
