  • Title: Random quasi-phase-matched second-harmonic generation in periodically poled lithium tantalate.
    Author: Stivala S, Busacca AC, Pasquazi A, Oliveri RL, Morandotti R, Assanto G.
    Journal: Opt Lett; 2010 Feb 01; 35(3):363-5. PubMed ID: 20125722.
    Abstract:
    We observe second harmonic generation via random quasi-phase-matching in a 2.0 mum periodically poled, 1-cm-long, z-cut lithium tantalate. Away from resonance, the harmonic output profiles exhibit a characteristic pattern stemming from a stochastic domain distribution and a quadratic growth with the fundamental excitation, as well as a broadband spectral response. The results are in good agreement with a simple model and numerical simulations in the undepleted regime, assuming an anisotropic spread of the random nonlinear component.
