Cascaded-χ<sup>(2)</sup>-interaction-based frequency-resolved optical gating in a periodically poled LiNbO<sub>3</sub> waveguide
We demonstrate a novel frequency-resolved optical gating (FROG) configuration based on cascaded second-order nonlinear interactions. Its implementation in a 2.6cm long quasi-phase-matched LiNbO<sub>3</sub> waveguide allowed high-quality retrieval of 2ps to 80fJ pulses at 1.56µm.
