Background
Semiconductor lasers are widely used in the fields of pumping solid lasers, laser communication, laser processing, laser medical treatment, military and the like because of the advantages of high power, light weight, small size, easiness in modulation and the like. With the continuous improvement of the output power of semiconductor laser, the semiconductor laser can be directly applied to the fields of material processing, laser medical treatment, military affairs and the like, but one of the main factors restricting the semiconductor laser manufacturing process has the problem of semiconductor laser bar coating and clamping. The key point for realizing the preparation and high efficiency of the semiconductor laser is that the clamping is convenient and rapid, the cavity surface contact pollution is avoided, and the double-sided coating is adopted. Aiming at bar fixtures clamping the same cavity length reported at present, the invention provides a bar coating fixture capable of clamping a plurality of semiconductor laser bar coating fixtures with different cavity lengths, which is convenient to clamp, free of contact pollution and capable of coating films on two sides.

A semiconductor laser bar coating fixture for clamping same-length semiconductors with different cavity lengths comprises a slide way plate 1, a slide way 2, a fixing plate 3 and a plurality of clamping strips 4.
The method is characterized in that:
the chute plate 1 includes: fixing holes 1-1, fixing holes 1-2, fixing holes 1-3, fixing holes 1-4, a slideway 2, and a bare coating area in the middle.
The chute 2 includes: eight pairs of slide ways which are symmetrical pairwise and have the same size, one end of each slide way is flush with the surface of the slide way plate, the slide way at the other end has a certain distance from the other surface, the semiconductor laser bar is just clamped to the end when being clamped, so that the coating cavity surfaces of all the bar are positioned at the same position, and the number of the slide ways is not limited to eight pairs, and can be more or less.
The fixing plate 3 includes: the fixing holes 3-1, the fixing holes 3-2, the fixing holes 3-3 and the fixing holes 3-4 are arranged in the middle of the slide way plate, the exposed size of the fixing holes is the same as that of the place without the slide way of the slide way plate, and when the fixing holes are fixed together, the slide way forms a complete clamping groove, so that the semiconductor laser bar is positioned at the same film coating position during turnover film coating, and the uniformity of the film is prevented from being influenced by 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. After clamping, the fixing is finished through the fixing holes 1-1 and 3-1, the fixing holes 1-2 and 3-2, the fixing holes 1-3 and 3-3, and the fixing holes 1-4 and 3-4.
The exposed rectangular area in the middle of the clamp is a semiconductor laser bar cavity surface coating area, after one surface coating is finished, the clamp can be turned over through the turning mechanism, two ends of the semiconductor laser bar are arranged in the corresponding slide ways, the bar slides to the other end of the slide way by gravity during turning, and meanwhile the bar can be kept at the same position, so that the uniformity of the film can be prevented from being influenced by different positions. The bar cavity surface coating area does not contact with anything in the clamping process of the clamp, no cavity surface pollution exists, and the clamping is convenient.
