Generation of Simultaneous Red, Green and Blue Light based on Cascaded Quasi-Phase-Matching in Periodically-Poled LiNbO3

\begin{abstract} We demonstrated simultaneous red, green, and blue light generation in periodically-poled lithium niobate crystals pumped with a single picosecond laser. The blue light was obtained by multiple-order quasi-phase-matched (QPM) second-harmonic generation of the near-infrared pump input. The other colors resulted from cascaded QPM sum-frequency generation between the pump and the signal or the idler waves generated by the first-order QPM optical parametric generation. The primary color peaks were temperature-insensitive, owing to the broadband optical parametric generation of participating infrared frequencies.
