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 clamps with the same cavity length or the same length reported at present, the invention provides a semiconductor laser bar coating clamp which can clamp a plurality of semiconductor laser bar coating clamps with different cavity lengths and different lengths, is convenient to clamp, has no contact pollution, and can perform double-sided coating.
Disclosure of Invention
The invention aims to provide a coating clamp for clamping semiconductor laser bar strips with different lengths and different cavity lengths.
A coating clamp for clamping semiconductor laser bar strips with different lengths and different cavity lengths comprises a step slideway plate 1, a step plate 2, a step slideway 3 and a plurality of clamping strips 4.
The method is characterized in that:
the step chute plate 1 comprises: the positioning hole 1-1, the positioning hole 1-2, the positioning hole 1-3, the positioning hole 1-4, the step slideway 3 and the middle exposed coating area.
The step plate 2 includes: positioning holes 2-1, positioning 2-2, positioning 2-3, positioning 2-4 and a middle exposed coating area. The exposed size is the same as the size of the place without the slide way of the step slide way plate, when the step slide way plate and the place without the slide way are fixed together, the slide way forms a complete clamping groove, the semiconductor laser bar is ensured to be positioned at the same film coating position during the turnover film coating, and the uniformity of the film is prevented from being influenced by different positions.
The step slide 3 includes: ten pairs of step slideways which are symmetrical pairwise and have the same size. One end of the step slide way is flush with the surface of the step slide way plate, the step slide way at the other end has a certain distance from the other surface, and 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 coating position, the number of the slide ways is not limited to ten pairs, and more or less.
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 the cavity surface from being polluted, and preventing the film material from being diffracted when the film is coated to prevent the positive and negative electrodes from being polluted by the film material.
The semiconductor laser bar with different lengths and different cavity lengths is clamped in a step slide 2 on a step slide plate 1 by two matched clamping strips, and the maximum cavity length of the bar is not more than the length of the step slide. After clamping, the positioning holes 1-1 and 2-1, the positioning holes 1-2 and 2-2, the positioning holes 1-3 and 2-3, and the positioning holes 1-4 and 2-4 are fixed, and the clamping is finished.
The middle exposed area of the fixture is a semiconductor laser bar cavity surface coating area, after one surface coating is finished, the fixture can be turned over through the turning mechanism, and because two ends of the semiconductor laser bar are arranged in the corresponding step slide ways, the fixture can slide to the other end of the step slide way by gravity during turning, and can be kept at the same position, and the influence on the uniformity of the film due to different positions can be prevented. 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.
