The invention relates to a fiber laser output light spot diameter testing device, which comprises an attenuation module, a light beam analyzer, a support and a computer, and is characterized in that the attenuation module and the light beam analyzer are fixed on the support, and one end, close to the light beam analyzer, of the attenuation module and a light inlet of the light beam analyzer are coaxially arranged; the light beam analyzer is electrically connected with the computer, and one end, far away from the light beam analyzer, of the attenuation module forms a light input end of the optical fiber laser to be measured. According to the device for testing the diameter of the output light spot of the optical fiber laser, an attenuation module, a light beam analyzer and a computer are arranged, the light input end of the optical fiber laser to be tested is formed at the end, away from the light beam analyzer, of the attenuation module, and the light beam analyzer is electrically connected with the computer; compared with an existing testing device, the device is simpler in structure, unnecessary equipment such as an optical splitter is omitted, and assembling operation is easier.
Description
technical field [0001] The invention relates to the technical field of laser detection, in particular to a device for testing the output spot diameter of a fiber laser. Background technique [0002] Direct Part Marking (DPM) refers to a marking technology that directly marks a code that can be recognized by a machine on the surface of a product. It can uniquely identify parts and components to achieve real-time, accurate acquisition and transparent management of product data. Commonly used direct parts marking methods include laser marking, mechanical needle impact, chemical etching and inkjet coding. Among them, laser marking technology using fiber lasers has been widely used in industry due to its convenient operation, flexibility, wide range of marking materials, high marking quality and precision, and high degree of automation. [0003] The output head specifications of fiber lasers vary according to the working system and power level of the laser. For high-power contin...
