    We show numerically the mutual dragging and locking together of intense fundamental and second-harmonic light beams propagating in second-order nonlinear media, and we discuss the potential applications of such effects for ...
  • 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)

    We 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 two-dimensional spatial solitary waves in a ¿ (2) medium 

    Torruellas, William; Stegeman, George; Torner Sabata, Lluís (IEEE Press, 1995)
    Conference report
    Open Access
    Cascaded 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 ...
  • 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)

    We 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 ...
  • Two-dimensional solitons with second-order nonlinearities 

    Torner Sabata, Lluís; Menyuk, Curtis; Torruellas, William; Stegeman, George (1995-01)
    Article

    We 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 ...
