Simultaneous broadband generation of second and third harmonics from chirped nonlinear photonic crystals
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.
