Cascaded-χ⁽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 - 80 fJ pulses at 1.56 μm.
