摘　　要：玻璃在外部激光的连续辐照下,由于材料的线性或非线性吸收激光能量不断淀积于玻璃体内,并在激光焦点区域形成热积累效应导致相关区域的玻璃材料转变成晶体。通过选择不同的激光器和玻璃基体,在玻璃体内能在二维或三维空间内控制晶体的形成。综述了国内外利用激光在玻璃材料中诱导非线性光学晶体的相关成果和最近进展以及作者在这方面开展的工作,并就激光选择性诱导晶体的理论作了一些简要介绍。Functional crystal growth induced by laser irradiation in glass materials has attracted a lot of interests because this method demonstrated potential applications for producing integrated optical devices.In most cases,the laser energy can be absorbed by the glass due to the linear or nonlinear absorption mechanism,which resulted in a locally effect for the glass melting and then for the growth of crystal in the focal point of the laser beam.We present here some recent advances related to the laser-induced-crystal technique and its applications for integrated optics.We also suggest future research directions in this field.
