Stable two -dimensional spatial solitons in heavy metal oxide glasses

2007

In this Communication, a stable self-confined propagation with ps near-infrared (NIR) pulses and over several Rayleigh lengths is demonstrated for the first time . Multiphoton absorption is shown to saturate the self-focusing response in a novel glass of the ternary system Nb2O5-O2-PbO (NPG) exhibiting a high refractive index (2-2.1) in the NIR and an energy gap of 3.52 eV. NPG belongs to the family of heavy metal oxides, widely studied for its fast and high nonlinearity in the infrared.

2D+1 spatial solitons in heavy metal oxide glass

2007

Two-dimensional self-confinement of near-infrared picosecond pulsed beams is demonstrated in a novel heavy metal-oxide glass, three-photon absorption being the stabilization mechanism to prevent catastrophic collapse.

Effetti trasversi nella propagazione di fasci ottici in vetri ad alto indice

2008

We investigate beam propagation in a novel Heavy Metal Oxide glass, reporting near infrared beam self-confinement and solitons, filamentation, interactions and conical emission at picoseconds and discussing them with the aid of a model.
