The utility model relates to the technical field of laser, in particular to a small-size high-power laser welding device, which comprises a box body, and a laser system, a condensation system, a power supply system and a control system which are arranged in the box body, and is characterized in that the condensation system is arranged in the box body; the laser system comprises an optical fiber coupling assembly, a diaphragm assembly, a resonant cavity and a feedback assembly which are connected in sequence; and the diaphragm assembly comprises two groups of totally reflecting mirrors which are oppositely arranged and form an included angle of 90 degrees, and is used for shortening the path of an optical path. The laser is amplified through mutual cooperation of the structures, and meanwhile, the size of the whole laser welding device is smaller through arrangement of a light path. 本实用新型涉及激光技术领域，尤其涉及一种小体积高功率的激光焊接器，所述小体积高功率的激光焊接器包括：箱体及安装于所述箱体内的激光系统、冷凝系统、电源系统和控制系统，其特征在于，所述激光系统包括顺次相连的光纤耦合组件、膜片组件、谐振腔、反馈组件；所述膜片组件包
