End face coating fixture for stripe-geometry semiconductor laser and application thereof

The invention provides an end face coating fixture for a stripe-geometry semiconductor laser and an application thereof. The end face coating fixture comprises a bar strip coating fixture and an auxiliary strip assembly tool. The bar strip coating fixture comprises a sliding part and a combination frame. The combination frame comprises a u-shaped bottom frame and an upper cross frame. Columns at the two sides of the u-shaped bottom frame are internally and respectively provided with slide channels. The two ends of the sliding part are respectively provided with an inverted T-shaped embedded part. The slide channels are matched with the T-shaped embedded parts. The u-shaped bottom frame and the central part of the sliding part are provided with replaceable bar strip clamping ends. The invention also provides an auxiliary strip assembly tool. The auxiliary strip assembly tool is cooperatively used together with the bar strip coating fixture during the bar strip assembling process. The fixture is modular in design, novel in structure, simple to machine, convenient in assembly and high in nimbleness. For bar strips of different types, the fixture is good in adaptability, strong in practicality, easy to clean and maintain, and long in service life.
