研究了BaO-B2 O3-SiO2系玻璃在CO2激光辐照下的表面改性和晶化过程，考察了激光功率、辐照时间和表面状态对玻璃表面改性和晶化的影响。通过施加超过0.40W的激光功率和超过300 s的照射时间来对玻璃表面进行改性。显微拉曼光谱和X射线衍射分析表明，在高功率激光作用下，样品中形成了β-BaB_2O_4（β-BBO）晶相。当β-BBO微米级颗粒分散在玻璃样品表面时，辐照区的晶化得到增强。在结晶区域中观察到的二次谐波产生的强度被发现主要取决于玻璃照射前的玻璃表面的条件。
The surface modification and crystallization process of BaO–B2O3–SiO2glass compositions when exposed to CO2laser irradiation was evaluated as a function of the laser power, irradiation time and surface condition. The glass surface was modified by the application of laser power exceeding 0.40W and an irradiation time of more than 300s. Micro-Raman and X-ray diffraction measurements revealed at high laser power the formation of β-BaB2O4(β-BBO) crystalline phase. The crystallization of the irradiated region was enhanced when β-BBO micrometer sized particles were dispersed on the surface of the glass sample. The intensity of the second harmonic generation observed in the crystallized region was found to depend mainly on the condition of the glassy surface prior to glass irradiation.
