A Gaussian laser beam is transformed into a rectangular cross section uniform beam by Fourier transformation. Many uniform rectangular beams have been developed by deformable mirror in laser processing. Adjustable and transformative methods of space mold have been researched and the effects between laser beam and materials have been tested, which can be used to improve the quality of laser machining. The results of the experiments show that laser space mold can be changed and used for RP processes.
