Second and third harmonic generation in disordered quadratic nonlinear media: Application to short-pulse characterization

Roppo, V; Wang, Wenjie; Kalinowski, Ksawery; Vilaseca, Ramon; Trull, Jose; Cojocaru, Crina; Staliunas, Kestutis; Krolikowski, Wieslaw; Kivshar, Yuri


We study parametric frequency conversion in quadratic nonlinear media with disordered ferroelectric domains. We demonstrate that disorder allows realizing broadband second- and third-harmonic generation via cascading of two second-order quasi-phase matched nonlinear processes. Application to short-pulse measurements is demonstrated.
