The invention discloses a film coating clamp for clamping semiconductor laser bars with the same length and different cavity lengths. The film coating clamp comprises a slideway plate 1, slideways 2,a fixing plate 3 and a plurality of clamping strips 4, the slideway plate 1 comprises a fixing hole 1-1, a fixing hole 1-2, a fixing hole 1-3, a fixing hole 1-4, the slideways 2 and a middle-exposed film coating area, the slideways 2 comprise eight pairs of slideways which are symmetrical pairwise and have the same size, the fixing plate 3 comprises a fixing hole 3-1, a fixing hole 3-2, a fixing hole 3-3, a fixing hole 3-4 and the middle-exposed film coating area, the plurality of clamping strips 4 are cuboids with the length equal to the length of the bars, the width of 1 mm and the height equal to the cavity length of the bars, each bar needs two clamping strips, each semiconductor laser bar with the same length and different cavity lengths clamped by the two matched clamping strips is clamped in the slideways 2, and the maximum cavity length of the clamped bars is equal to the length of the slideways, after clamping, fixing is carried out through the fixing hole 1-1 and the fixing hole 3-1, the fixing hole 1-2 and the fixing hole 3-2, the fixing hole 1-3 and the fixing hole 3-3, the fixing hole 1-4 and the fixing hole 3-4, and clamping is finished for film coating.
Description
technical field [0001] The invention relates to the technical field of semiconductor lasers, in particular to a coating fixture for clamping semiconductor laser bars with the same length and different cavity lengths. Background technique [0002] Semiconductor lasers are widely used in the fields of pumping solid-state lasers, laser communications, laser processing, laser medical treatment, and military because of their advantages such as high power, light weight, small size, and easy modulation. With the continuous improvement of the output power of semiconductor lasers, it can be directly applied to the fields of material processing, laser medical treatment and military affairs, but one of the most important factors restricting the semiconductor laser manufacturing process is the problem of semiconductor laser bar coating and clamping. Convenient and fast loading, no cavity surface contact pollution and double-sided coating are the key to realize semiconductor laser prepar...
