Observation of mutual trapping and dragging of two-dimensional spatial solitary waves in a quadratic medium
Torruellas, William; Wang, Zou; Torner Sabata, Lluís; Stegeman, George (1995-09)
Article
Accés restringit per política de l'editorialWe report experimental evidence for trapping of two-dimensional (2 + 1) spatial solitary waves in a KTP crystal resulting from its second-order nonlinearity. In addition, dragging of the solitary beams is observed as a ... -
Observation of self-focusing of light mediated by cubic nonlinearities in potassium titanyl phosphate
Carrasco Rodríguez, Sílvia; Kim, Hongki; Stegeman, George; Loza Álvarez, Pablo; Torner Sabata, Lluís (2002-11)
Article
Accés restringit per política de l'editorialWe report our observations of the transient self-narrowing of light beams mediated by dominant Kerr nonlinearities and two-photon absorption in a bulk potassium titanyl phosphate crystal near conditions for second-harmonic ... -
Observation of two-dimensional spatial solitary waves in a quadratic medium.
Torruellas, William; Wang, Zou; Hagan, Dave; VanStryland, Eric; Stegeman, George; Torner Sabata, Lluís; Menyuk, Curtis (1995-06)
Article
Accés restringit per política de l'editorialWe report the first experimental demonstration of two-dimensional spatial solitary waves in second-order nonlinear optical material. When an intense optical beam is focused into a phase-matchable second-order nonlinear ... -
Observation of two-dimensional spatial solitary waves in a ¿ (2) medium
Torruellas, William; Stegeman, George; Torner Sabata, Lluís (IEEE Press, 1995)
Text en actes de congrés
Accés obertCascaded second order nonlinear processes offer a new range of opportunities. Indeed we have shown that under near phase matching conditions, the associated nonlinear phase distortion to the fundamental wave depletion ... -
Second-harmonic generation tuning curves with narrow, high-intensity beams for quasiphase-matched potassium titanyl phosphate
Kim, Hongki; Jankovic, Ladislav; Stegeman, George; Katz, Mordechai; Carrasco, Silvia; Torner Sabata, Lluís (2002-08)
Article
Accés restringit per política de l'editorialThe tuning curves with temperature and incidence angle for second-harmonic generation were asymmetrically distorted and broadened with increasing intensity for narrow input fundamental beams in periodically poled KTiOPO4 ... -
Two-dimensional solitons with second-order nonlinearities
Torner Sabata, Lluís; Menyuk, Curtis; Torruellas, William; Stegeman, George (1995-01)
Article
Accés restringit per política de l'editorialWe investigate the propagation of intense Gaussian beams in materials with quadratic nonlinearity. Excitation of (2 + 1) solitons is numerically predicted at finite phase mismatch and in the presence of linear walk-off ...
