title: Cascaded-chi(2)-interaction-based frequency-resolved optical gating in a periodically poled LiNbO3 waveguide.
abstract: We demonstrate a novel frequency-resolved optical gating (FROG) configuration based on cascaded second-order nonlinear interactions. Its implementation in a 2.6 cm long quasi-phase-matched LiNbO3 waveguide allowed high-quality retrieval of 2 ps to 80 fJ pulses at 1.56 microm.
