Horizontal-array high-power semiconductor laser capable of replacing chip

The invention discloses a horizontal-array high-power semiconductor laser capable of replacing a chip, which comprises a refrigerator. A liquid passage is arranged in the refrigerator; the upper end face of the refrigerator is a horizontal mounting surface; a plurality of laser chip mounting components, which are parallel to and independent from one another, are arranged on the horizontal mounting surface; each laser chip mounting component consists of the chip, and a lower insulating strip, a positive heat sink, an upper insulating strip, a chip cathode connection piece and an electrode connection piece which are sequentially laminated and fixed from bottom to top; the anode surfaces of the chips are connected with the positive heat sinks, while cathode surfaces are connected with the electrode connection pieces; and fixed plates are arranged at the upper ends of the plurality of laser chip mounting components. In the horizontal-array high-power semiconductor laser capable of replacing the chip, the pluralit
