Title: Ptychographic amplitude and phase reconstruction of bichromatic vortex beams

Abstract

We experimentally demonstrate that ptychographic coherent diffractive imaging can be used to simultaneously characterize the amplitude and phase of bichromatic orbital angular momenta-shaped vortex beams, which consist of a fundamental field, together with its copropagating second-harmonic field. In contrast to most other orbital angular momentum characterization methods, this approach solves for the complex field of a hyperspectral beam. Lastly, this technique can also be used to characterize other phase-structured illumination beams, and, in the future, will be able to be extended to other complex fields in the extreme ultraviolet or X-ray spectral regions, as well as to matter waves.

Figure 1 Figure 1: Experimental schematic for simultaneously imaging an orbital angular momentum beam and its second harmonic. A laser beam with center wavelength 790 nm propagates through a spiral phase plate (SPP) of $\ell$= 2 and is focused to a BBO crystal using a lens (L1). The fundamental and second harmonicmore » beams both illuminate a resolution test target, and are Fourier transformed via another lens (L2). The target is moved with respect to the two beams, and diffraction patterns are collected on a CMOS camera. Theoretically rendered helical wavefronts of red (790 nm) and blue (395 nm) OAM beams are shown at the top. M1 and M2: mirrors.« less
