The fixing plate 3 includes: the middle of the fifth fixing hole 3-1, the sixth fixing hole 3-2, the seventh fixing hole 3-3 and the eighth fixing hole 3-4 is an exposed cavity surface coating area, the exposed size is the same as the size of a place without a slide way of the slide way plate, and when the fifth fixing hole 3-1, the sixth fixing hole 3-2, the seventh fixing hole 3-3 and the eighth fixing hole are fixed together, the slide way forms a complete clamping groove, so that the semiconductor laser bar is positioned at the same coating position during turnover coating, and the uniformity of the film is prevented from being influenced due to different positions.
The clamping strips 4 are cuboids with a length equal to the length of a bar, a width of 1mm and a height equal to the length of a bar cavity, and each bar needs two clamping strips. The clamping strips 4 are used for preventing tools such as tweezers from directly touching the cavity surface to prevent pollution and preventing the film material from diffracting during film coating to prevent the positive and negative electrodes from being polluted by the film material.
The semiconductor laser bar with the same length and different cavity lengths, which is clamped by two matched clamping strips, is clamped in a slide 2 on a slide plate 1, and the maximum cavity length of the clamping bar does not exceed the length of the slide.
