Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figure 1-4 , A variable power laser beam shaping optical system, comprising an incident light source 1, an aspheric lens 2, aspheric lens 2 3, and aspheric lens 3 arranged along the optical path in sequence, the aspheric lens 2, aspheric Lens two 3 and aspheric lens three 4 are even-order aspheric lenses with complex power distribution. Under any magnification within the system's variable magnification range, the system transmits incident light from different positions to the final optical surface and emits light The location satisfies the following relationship:

Abstract

The invention relates to the technical field of optical design and laser beam shaping, in particular to a variable-magnification laser beam shaping optical system so as to solve defects in the prior art. The system comprises an incident light source, and an aspheric lens I, an aspheric lens II and an aspheric lens III which are sequentially arranged along a light path, wherein the aspheric lens I,the aspheric lens II and the aspheric lens III are even aspheric lenses with complex focal power distribution; and under any multiplying power in a system zooming range, the system transmits the incident light at different positions to the final optical surface and emits the light. According to the variable-magnification laser beam shaping system, continuous variable-magnification flat-topped beam output can be achieved, good collimation is achieved, and space energy distribution and phase distribution of laser beams are accurately regulated and controlled.
