Observation of self-focusing of light mediated by cubic nonlinearities in potassium titanyl phosphate Carrasco Rodríguez, Sílvia; Kim, Hongki; Stegeman, George; Loza Alvarez, Pablo; Torner Sabata, Lluís (2002-11)
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 ...
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)
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 ...
