The research results of optoelectronic functional crystals are the source of new materials and new devices in the contemporary microelectronics and optoelectronic industries and play an important role in the national economy and national defense construction. The project of “Research on the Structure and Function, Molecular Design, Microstructure Design and Preparation Process of Photoelectric Functional Crystal” completed the expected planned tasks well in the previous two years and made some progress in several important aspects. Among them, breakthroughs were made in deep deep ultraviolet non-linear optical crystals KBBF and KABO crystals invented by the research team of this project. Laser effective power output of wavelength 200nm was achieved in KBBF crystal. KABO has been available for practically centimeter grade crystals , And achieved a laser output wavelength of 266nm; the use of “one-dimensional artificial quasi-crystal” successfully developed at the same time can output green and ultraviolet light and red and blue two types of all solid-state dual-wavelength laser prototype for the next three years The realization of multiwavelength all-solid-state lasers and the establishment of coupled and cascaded nonlinear optics have opened up the way. Through the combination of research groups within the project, breakthrough progress has been made in the practical use of YCOB crystals and has been internationally recognized. Ferroelectrics is one side, and the research of heterojunctions with semiconductors, superconductors and ferromagnets as the other side has also made significant progress. The achievement of these achievements has created favorable conditions for the realization of the five-year expected goal of this project in the next three years.
