Two-dimensional nonlinear beam shaping.

We develop a technique for two-dimensional arbitrary wavefront shaping in quadratic nonlinear crystals by using binary nonlinear computer generated holograms. The method is based on transverse illumination of a binary modulated nonlinear photonic crystal, where the phase matching is partially satisfied through the nonlinear Raman-Nath process. We demonstrate the method experimentally showing a ...

Beam shaping using genetically optimized two-dimensional photonic crystals.

We propose the use of two-dimensional (2D) photonic crystals (PhCs) with engineered defects for the generation of an arbitrary-profile beam from a focused input beam. The cylindrical harmonics expansion of complex-source beams is derived and used to compute the scattered wave function of a 2D PhC via the multiple scattering method. The beam shaping problem is then solved using a genetic algorit...

Transverse Ion Beam Shaping Using Nonlinear Optics

Taking an advantage of the unique capabilities of heavy ion beams and continuously increasing beam intensity, many successful experiments on high energy density (HED) matter have been carried out at GSI over the past few years. New fascinating experimental proposals such as investigation of equation-of-state of matter under extreme conditions [1] and generation of metallic hydrogen utilizing io...

Beam Shaping and Control with Nonlinear Optics

We demonstrate the feasibility of strong (up to atomic fields) and super-short (fewor even sub-femtosecond) sub-cycle (non-oscillating) electromagnetic solitons -EM bubbles (EMBs) in a gas of two-level atoms, as well as EMBs and pre-ionization shock waves in classically nonlinear atoms. We show that EMBs can be generated by existing sources of radiation, including sub-picosecond half-cycle puls...

Nonlinear Beam Shaping with Plasmonic Metasurfaces

We present here a method for generating second-harmonic beams with tailored beam profiles using nonlinear metasurfaces based on split ring resonators. By manipulating both the phase and the amplitude of the quadratic nonlinear coefficient locally, at the single inclusion level, the emitted secondharmonic wavefront is perfectly controlled. These concepts are demonstrated experimentally by the fa...
