Flat-top laser flat-top position determination method and system

The invention relates to a method and system for determining the flat top position of flat-top laser, and the method comprises the steps: enabling the flat-top laser generated by a laser generation device to sequentially penetrate through a diaphragm hole of a diaphragm and a lens, and enabling the diaphragm hole of the diaphragm to be imaged on an imaging device; adjusting a first distance between a diaphragm hole of the diaphragm and the lens to a preset value; and a second distance between the lens and the imaging device is adjusted, so that the imaging of the diaphragm hole accords with the target definition, and the position, corresponding to the imaging device, of the diaphragm hole which accords with the target definition serves as the flat-topped position of the flat-topped laser. According to the technical scheme, the efficiency of determining the flat-topped position of the flat-topped laser can be improved. 本申请涉及平顶激光平顶位确定方法及系统，所述方法包括：使所述激光产生装置产生的平顶激光依次透过所述光阑的光阑孔和所述透镜，并使所述光阑的光阑孔在所述成像装置上成像；调整所述光阑的光阑孔
