Description

TECHNICAL FIELD

[0001] The present application relates to a kind of microchannel laser array fast correction device and correction method, belong to the technical field of semiconductor laser package. BACKGROUND

[0002] In recent years, due to the semiconductor laser has extremely high output power, good beam quality, compact mechanism, longer life and small size, light weight, efficiency and reliability and other characteristics, it has been more and more widely used in pumping, medical, display lighting, laser processing and military and other fields. With the gradual optimization of high-power semiconductor laser chip structure and the progress of packaging technology, the preparation and application of microchannel laser with output power reaching kilowatt are also rapidly growing. With the improvement of user demand and the in-depth research, the performance of high-power microchannel semiconductor laser has been rapidly improved.

[0003] In order to obtain high-power laser output, while achieving good heat dissipation requirements, a plurality of microchannel lasers need to be neatly stacked together through a series of components, and such stacked laser is commonly known as array. Since the number of each group of stacked laser is relatively large, the lasers are fixed by screws, and during stacking or in the process of stacking, it is inevitable to have different degrees of deflection. Since the size of microchannel laser is small, there is a liquid hole on the laser, and all the liquid holes of the laser need to be kept closed, and the deflection of the stacked array will cause poor sealing of the laser and liquid leakage, resulting in contamination or damage of the laser. Therefore, the stacked array needs to be corrected to restore the vertical state of the deflected stacked array.

[0004] The commonly used correction method for the stacked array is to place the stacked array on a platform, then take out a long-shaped pressing block, place it on the other side of the stacked array, and then press the pressing block repeatedly with force, so that the deflected laser is extruded to the normal position, so that the whole stacked array is restored to the vertical state. The correction device is simple but labor-intensive and low in efficiency, and the correction accuracy and consistency of the stacked array are poor, which cannot guarantee that all the corrected stacked arrays maintain the same state. And in the operation process, the operator directly contacts with the stacked array, and human factors can easily cause contamination and damage of the laser. Therefore, a microchannel laser stacked array correction device with simple structure, convenient operation, high production efficiency and high precision is designed to solve the problems existing in the current laser stacked array correction work.
