We report a new diffractive beam shaper that transforms an incident Gaussian beam into a pseudo-nondiffracting beam with a relatively flat on-axis intensity distribution in the propagation range. The compact single-element beam shaper with a quasicontinuous phase structure demonstrated beam-forming efficiency of 87.5%. The effects of misalignment and beam size error on beam-forming quality are also addressed.
