Axial sub-Fourier focusing of an optical beam

PLUTO / PLUTO-2 Spatial Light Modulators
Beam Shaping / Beam Steering

Authors: Thomas Zacharias and Barak Hadad and Alon Bahabad and Yaniv Eliezer
Abstract:
“We demonstrate experimentally the generation of an optical beam having an axial focusing that is narrower than the Fourier limit. The beam is constructed from a superposition of Bessel beams with different longitudinal wave vectors, realizing a super-oscillatory axial intensity distribution. Such beams can be useful for microscopy and for optical particle manipulation.”
