The invention relates to a plane grating and a single-beam incident three-dimensional magneto-optical trap system comprising the plane grating, the plane grating comprises three regions with different etching directions: an etching region I, an etching region II and an etching region III, and the grating structure parameters of the etching region I, the etching region II and the etching region III are completely consistent. The grating etching directions of the three etching areas form a triangular array, and the included angle between every two etching areas is 60 degrees. The invention can solve the problems that an existing magneto-optical trap system adopts six beams of laser to perform two-to-two correlation, fluctuation mutual interference exists among the six beams of laser, the system structure is complex, miniaturization is difficult and the like, and the invention can be applied to quantum precision measurement systems such as small-sized atom interference gyroscopes and gravimeters and future integ
