Photon avalanche up-conversion in NdAl(BO) nanoparticles excited at 1064 nm
Jefferson F. da Silva, Rodrigo F. da Silva, Emanuel P. Santos +2
We report efficient non-resonant ground state excitation at 1064 nm of trivalent neodymium (Nd) ions in stoichiometric neodymium aluminum borate NdAl(BO) nanopar…
Probing the reciprocal lattice associated with a triangular slit to determine the orbital angular momentum for a photon
W. C. Soares, A. L. Moura, Askery Canabarro +7
The orbital angular momentum conservation of light reveals different diffraction patterns univocally dependent on the topological charge of the incident light beam when passing thr…
Lévy flights for light in ordered lasers
Erick G. Rocha, Emanuel P. Santos, Bruno J. dos Santos +4
Lévy flights for light have been demonstrated in disordered systems with and without optical gain, and remained unobserved in ordered ones. In the present letter, we investigate, n…
