    • Complex soliton-like pattern generation in potassium niobate due to noisy, high intensity, input beams 

      Jankovic, L; Polyakov, S; Stegeman, G; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís; Bosshard, Ch; Gunter, P (2003-09)
      Article
      Restricted access - publisher's policy
      We report the generation of complex soliton-like patterns in non-critically-phase-matched potassium niobate which occur in random spatial patterns from shot-to-shot. Up to five spots have been generated at input intensities ...

    • Properties of quadratic multi-soliton generation near phase-match in PPKTP 

      Polyakov, S; Jankovic, L; Kim, H; Stegeman, G; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís; Katz, M (2003-06)
      Article
      Restricted access - publisher's policy
      The properties of the multi-quadratic-soliton generation process have been investigated both theoretically and experimentally near and on phase-match in non-critically-phase-matched, periodically poled, potassium titanyl ...
    • Second harmonic generation tuning curves in quasiphase-matched potassium titanyl phosphate with narrow, high-intensity beams 

      Katz, M; Eger, D; Kim, H; Jankovic, L; Stegeman, G; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís (American Institute of Physics (AIP), 2003-06)
      Article
      Restricted access - publisher's policy
      The second harmonic generation (SHG) tuning curves with temperature and angle of incidence were measured in periodically poled KTiOPO4 for narrow fundamental beams at intensities typical of quadratic soliton generation. ...
    • Second harmonic generation, beam dynamics and spatial soliton generation in PPKTP 

      Kim, H; Jankovic, L; Stegeman, G; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís; Katz, M; Eger, D (2003-03)
      Article
      Restricted access - publisher's policy
      Spatial solitons were investigated in periodically poled KTiOPO4 under conditions of second harmonic generation and many new features associated with soliton generation in quasi-phase-matched samples were observed .The ...
    • Trapping of light beams and formation of spatial solitary waves in quadratic nonlinear media 

      Torner Sabata, Lluís; Torruellas, W; Stegeman, G; Menyuk, C; Wright, E (Institute of Electrical and Electronics Engineers (IEEE), 1996)
      Conference report
      Open Access
      Summary form only given. In this paper we report the outcome of our comprehensive investigations to study the dynamics of the beam trapping in both bulk crystals and optical planar waveguides made of quadratic nonlinear ...
