We present a source of red, green and blue light (RGB source), produced by pumping with a pulsed Nd:YAG laser a periodically poled lithium niobate crystal that has two poling periodicities. The first section produces through optical parametric generation a ∼ 1.43 μ m signal and the last section simultaneously produces the second (near-IR) and third harmonic (blue) of the signal obtained from the first section. The green and red beams are the result of non-phase-matched second harmonic generation of the pump and sum-frequency generation between the pump and signal.
