An adjacent sequence iteration method for designing a diffractive element with function of controlling wave-front propagation is presented, and with this method a diffractive optical element for focusing a diode laser beam into large depth of focus is designed. The simulation calculation with the designed element indicates that the design is successful. The designed element is fabricated by means of photolithography and ion etching techniques and tested by a diode laser beam.
