摘　　要：用单向光入射和单次曝光的激光全息技术制作了类金刚石结构,此类金刚石结构有宽完全带隙和低介质折射率要求等优点.在同一种光束配置下,引入恰当的匹配棱镜,用激光全息技术制作了大面积的类金刚石光学晶格不同晶面取向的亚微米周期结构.满足如负折射效应等研究中所需的特殊晶面取向要求.A diamond-like structure, which has a large complete photonic band gap and needs only a low refractive index contrast to open the complete photonic band gap, have been fabricated using four umbrellalike beams. By use of special prism to match the beams, diamond-like crystals with special surface orientations have been fabricated. The capability and feasibility of this method have been demonstrated by the fabrication of long-range ordered dlamond-like microstructures with （114） and （110） surface orientation. The fabrication of large crystals with adjustable surface orientations will be advantageous to the systematic investigation of photonic properties such as negative reflection etc.
