Description

technical field [0001] The invention relates to a measuring device, especially a device for measuring the vertical divergence angle of a high-power laser diode array. Background technique [0002] At present, high-power laser diode arrays have been widely used in the production of industrial lasers, and based on the advantages of laser diode arrays such as small size, high power, high efficiency, and good reliability, high-power laser diodes are also used in industry, medical, military, etc. and other fields, the scope of application is extremely wide. [0003] However, since the light field distribution of a high-power laser diode array is very complex and asymmetric, generally speaking, the output light waves of the light-emitting units on it are incoherent, and the light intensity in the far-field region can be a simple superposition of the light intensity of a single light-emitting unit. For a typical high-power laser diode array, the divergence angle of the vertical (t...
