The invention discloses a coating fixture for clamping semiconductor laser bars with different lengths and different cavity lengths. The coating fixture comprises a step slideway plate 1, a step plate2, step slideways 3 and a plurality of clamping bars 4, wherein the step slideway plate 1 comprises positioning holes 1-1, 1-2, 1-3 and 1-4, a step slideway 3 and a coating area exposed in the middle; the step plate 2 comprises positioning holes 2-1, 2-2, 2-3 and 2-4 and a coating area exposed in the middle; the step slideways 3 comprise ten pairs of step slideways which are symmetrical pairwiseand have the same size; the clamping bars 4 are cuboids with the length equal to the length of a bar, the width of 1 mm and the height equal to the cavity length of the bar, and each bar needs to be clamped by two clamping bars. Semiconductor laser bars with different lengths and different cavity lengths, which are clamped by two matched clamping bars, are clamped in the step slideways 3. And after clamping, fixing is carried out through the positioning hole 1-1 and the positioning hole 2-1, the positioning hole 1-2 and the positioning hole 2-2, the positioning hole 1-3 and the positioning hole 2-3, and the positioning hole 1-4 and the positioning hole 2-4, and after clamping is finished, film coating is prepared.
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 different lengths and 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 preparation an...
