We report on simultaneous sum-frequency mixing and doubling of C-band and ∼ 980 n m laser sources using a single segmented periodically poled lithium niobate (PPLN) crystal in a single-pass configuration. Our theoretical analysis on the spectral outputs show that a proper design of a five-segment single PPLN crystal has potential to generate violet, blue, green, and orange wavelengths by simultaneous sum-frequency and second-harmonic generation processes. Such a design has promising potential for a compact, tunable multicolored laser that can find various applications such as in biomedicine, visible light communications, laser-based color displays, and sensing.
