Summary:The invention provides a technical scheme of a luminous point rotating, densely arraying and shaping device of a semiconductor laser. The technical scheme comprises a semiconductor laser chip, a heat sink, a fast axis collimating lens, a cylindrical lens group and a rectangular prism group, wherein the semiconductor laser chip is packaged on the heat sink; laser emitted by the semiconductor laser chip penetrates through the fast axis collimating lens, the rectangular prism group and the cylindrical lens group in sequence and then is ejected. According to the technical scheme, the homogenization of fast and slow axis optical beam quality can be realized by the rotation of optical beams, the structure is simple, and elements are easy to process.
