摘要

Ultrabroadband laser sources are highly desirable in a wide variety of modern science disciplines ranging from physics,chemistry and materials science to information communications and processing.Here we present the design and fabrication of a chirped periodically poled lithium niobate(CPPLN)nonlinear photonic crystal that supports multiple orders of quasiphase matching with finite bandwidth and allows for the simultaneous broadband generation of second and third harmonics with high conversion efficiency.Moreover,the chirp rate has a significant influence on the conversion efficiency and bandwidth.The CPPLN scheme offers a promising approach for the construction of short-wavelength laser sources and enables the generation of the three primary colors—red,green and blue—from a single crystal,which may have potential applications in large-screen laser displays.
