We demonstrate a ring-shaped Bessel-like photonic lattice akin to a photonic bandgap fiber with a low-index core. While the lattice is optically induced with self-defocusing nonlinearity, bandgap guidance of a probe beam is clearly observed.
Propagating orthogonally polarized probe and coupling lasers through a Cesium beam we explored two closed transitions. Electromagnetically induced absorption and absorption within transparency were measured on one line, electromagnetically induced transparency on the other one.
We observe experimentally nonlinear localization of beams in two-dimensional modulated Bessel-type photonic lattices with self-focusing nonlinear response.
We demonstrate experimentally all-optical beam steering in modulated photonic lattices produced by three wave interference in photorefractive crystals. We show that high spatial resolution can be achieved by combining dynamic beam steering with nonlinear self-localization.
We present the first observation of Thomson backscattered light from laser-accelerated electrons. Time-resolved electron spectra during the acceleration process have been obtained.
We report the first experimental demonstration of ring-shaped Bessel-like photonic lattices and rotary solitons in such lattices. Transition from discrete diffraction to single-channel linear guidance or nonlinear self-waveguiding is clearly observed.
