In the anti-Stokes excitation of trivalent rare-earth ions (RE3+), the excitation photons energy is smaller than that of a given absorption transition, and the energy mismatch can be compensated by phonons annihilation from the host lattice. Since th

Abstract Random lasers (RLs) are remarkable experimental platforms to advance the understanding of complex systems phenomena, such as the replica-symmetry-breaking (RSB) spin glass phase, dynamics modes correlations, and turbulence. Here we study the

Random Lasers, Complex Systems and the Nobel Prize in Physics 2021
Autor: Anderson S. L. Gomes, André L. Moura, Cid B. de Araújo, Ernesto P. Raposo
Publikováno v: Conference on Lasers and Electro-Optics.
Random lasers are recognized as open cavity complex systems emitting coherent radiation with interesting properties. I shall describe its applications to studies of spin-glass, turbulence and its relation to the Nobel Prize in Physics 2021

Photon-Avalanche-Like Excitation at 1064 nm of Nd3+ in NdxY1.00-xAl3(BO3)4 Particles
Autor: Rodrigo F. da Silva, Daniel F. Luz, Célio V. T. Maciel, Gabriela S. Soares, Emanuel P. Santos, Lauro J. Q. Maia, Carlos Jacinto, André L. Moura
Publikováno v: Latin America Optics and Photonics (LAOP) Conference 2022.
We demonstrate the feasibility of an unconventional excitation of Nd3+ at 1064 nm by a photon-avalanche-like mechanism, which involves an energy looping due to energy transfer among excited Nd3+ followed by resonant excited-state absorption.
