The light source module 1 is configured to emit laser with a certain wavelength, the optical component 2 is disposed at a laser emitting end of the light source module 1, and the optical component 2 may be disposed in a housing of the light source module 1 or outside the housing of the light source module 1. After passing through the optical component 2, the laser is modulated into a light spot with a preset size and/or a preset shape, the size of the light spot is smaller than that of the exit through hole 31, the optical component 2 may only modulate the size or shape of the laser beam, or may modulate the size and shape at the same time, for example, the modulated laser forms a square light spot with a side length of d, or forms a circular light spot with a diameter of d, and the shape of the light spot may be the same as that of the exit through hole 31, so that the light spot can be transmitted through any position of the exit through hole 31. For example, if the exit via 31 is a large square with a side length of 40mm, the light spot may be in a small square shape of 4mm × 4mm, that is, the exit via 31 is divided into a plurality of sub-exit units arranged in a matrix, the sub-exit units have the same shape and size as the light spot, and the light spot can be transmitted from the sub-exit units at different positions. The laser emitted by the light source module 1 is a gaussian beam, and in a preferred embodiment, the laser is modulated by the optical component 2 to form a flat-top beam, so that discomfort of a human body due to local high temperature caused by uneven energy distribution when the gaussian beam acts on a target surface is avoided.

In other words, when the laser cosmetic apparatus is operated, the light spot can be controlled to exit from the sub-exit unit of the exit through hole 31, the apparatus MCU automatically converts the position coordinates of the area to be exited into a corresponding voltage value, and controls the first motor 411 and/or the second motor 421 to drive the X-axis galvanometer 412 and/or the Y-axis galvanometer 422 to deflect by a corresponding angle based on the voltage value, thereby ensuring that the light spot irradiates the target surface through the exit area. It is understood that the areas where the light spots exit from the exit through holes 31 are different, and the deflection angles of the X-axis galvanometer 412 and/or the Y-axis galvanometer 422 are also different. In addition, the size of facula is less than the size of exit through-hole 31, can control the facula and jet out from different sub-exit unit at different time, even temperature-sensing head 3 lasts and contacts a certain target surface, the facula emergence is regional to change and can avoid its certain region that lasts the target surface, does benefit to the heat dissipation.
