摘　　要：作为新型非线性光学材料，钙－稀土硼酸盐晶体Ｃａ４ＲＯ（ＢＯ３）３（Ｒ－Ｌａ３＋、Ｎｄ３＋、Ｓｍ３＋Ｇｄ３＋Ｙ３＋Ｅｒ３＋、Ｔｂ３＋、Ｌｕ３+）近来引起了广泛的重视．该系列晶体属非中心对称的单斜晶系，空间群Ｃｍ．本文综述了上述晶体的结构和生长研究的进展。总结了晶体的线性光学／非线性光学性能以及掺杂晶体的激光自倍频性能，指出这些晶体在非线性光学领域潜在的应用前景．The isostructural calcium rare-earth oxyborates Ca_4RO(BO_3)_3 (R-La^3+ I Nd3^+, Sin3^+ ,Gd3^+, Y3^+, Er^3+, Tb^3+, Lu~_3+) as nonlinear optical materials have attracted great attentions recently. They belong to the monoclinic crystallographic system with space group Cm. The progresson the research of their structures and crystal growth was reviewed, and their linear/nonlinearoptical properties and self-frequency doubling properties were also summarized in detail. It wassuggested that these crystals possess potential applications in frequency conversion.
