Abstract

Three kinds of high efficiency phase-type fractal zone plates were rapidly (in tens of minutes) fabricated by femtosecond laser two-photon photopolymerization. Their theoretical maximal diffractive efficiencies of 24.5%, 12.52%, and 18.76% were predicted both by numerical simulation and analytical deduction and were verified by the measured values of 20.5%, 9.1%, and 13%, respectively. The characteristic of multifoci and the improved imaging ability for phase-type fractal lens was also demonstrated. Moreover, to further enhance the diffractive efficiency, a four-level fractal phase lens, whose diffraction efficiency reached as high as 37.6%, was proposed and realized.
