Enhanced fourth harmonic generation via nonlinear Cerenkov interaction in periodically poled lithium niobate crystal

Chen, Xin; Switkowski, Krzysztof; Hu, Xiaopeng; Krolikowski, Wieslaw; Sheng, Yan


We introduce a custom-cut periodically poled ferroelectric crystal for the phase matching of multistep cascading frequency conversion processes. Our approach involves combination of collinear second harmonic generation and transverse sum frequency mixing via the total internal reflection of the fundamental and collinear second harmonic beams. As a proof of concept we demonstrate multiple frequency generation with an enhanced fourth harmonic signal in a one-dimensional periodically poled LiNbO3...[Show more]
