Laser automatic test equipment

Abstract

The invention discloses laser automatic test equipment, which comprises an equipment shell and an upper cover arranged on the equipment shell, wherein the equipment shell is of a rectangular box bodystructure, the upper side face and the left side face of the box body of the equipment shell are open, the upper cover is rotationally installed on the right side wall of the equipment shell, a startbutton, a stop button and an audible and visual alarm are sequentially arranged on the front side surface of the equipment shell from left to right, an alternating current power supply socket is fixedly arranged at the right end of the rear side surface of the equipment shell, an optical flat plate is fixedly arranged on the bottom surface of the equipment shell and is a rectangular flat plate, and a 24V power supply is fixedly arranged on the right side wall of the equipment shell. According to the invention, the laser automatic test equipment is high in automation degree, all function testscan be completed through one-key operation, the test content is complete, the purpose of quickly and automatically finding out the maximum power point P is achieved by applying a unique algorithm, andthe test coaxiality of a 10 mm diaphragm is ensured by virtue of a limiting plate structure, so that the measurement accuracy of the device is ensured.

Description

technical field [0001] The invention relates to the technical field related to laser testing, in particular to laser automatic testing equipment. Background technique [0002] A laser is a device capable of emitting laser light. In 1954, the first microwave quantum amplifier was manufactured and a highly coherent microwave beam was obtained. In 1958, A.L. Showlow and C.H. Towns extended the principle of microwave quantum amplifiers to the optical frequency range. In 1960, T.H. Maiman and others made the first ruby ​​laser. In 1961, A. Jia Wen and others made a helium-neon laser. In 1962, R.N. Hall and others created a gallium arsenide semiconductor laser. In the future, there will be more and more types of lasers. According to the working medium, lasers can be divided into four categories: gas lasers, solid-state lasers, semiconductor lasers and dye lasers. Recently, free electron lasers have also been developed, and high-power lasers are usually pulsed outputs; they nee...

Problems solved by technology

Recently, free electron lasers have also been developed, and high-power lasers are usually pulsed outputs; they need to be tested for function and performance before leaving the factory, but traditional lasers mainly rely on labor and simple manual tooling, and the human factors of the test results The impact is large, and the consistency of repeated tests is poor, which will bring product quality risks and operator safety risks
