| 摘 要： | 为了制备Yb3+掺杂硅酸盐激光玻璃,并对其激光特性进行分析,采用富氧气氛下的非化学气相沉积高温熔融工艺,通过Fuchbauer-Ladenburger方法,进行了理论分析和实验验证,取得了所制备硅酸盐激光玻璃的吸收光谱和荧光光谱数据。结果表明,在850nm～1100nm近红外波段为吸收区域,有一宽带吸收峰;吸收主峰位于978nm,次峰位于919nm;其荧光主峰位于1018nm,次峰位于970nm,并理论计算了Yb3+的吸收截面面积、受激发射截面面积及其荧光寿命等特征参量。这一结果对硅酸盐激光玻璃的特性分析是有帮助的,所制备的玻璃材料能够满足激光玻璃的使用要求。

| Abstract: | In order to prepare Yb3+-doped silicate laser glass and analyze its laser characteristics, based on the no-chemical vapor deposition high temperature melting process in an oxygen-enriched atmosphere, the data of the absorption and fluorescence spectra of the glass were obtained according to Fuchbauer-Ladenburger(F-L) method. It can be concluded that there are board-band absorption peaks in the absorption band of 850nm~1100nm near-infrared wavelengths. The main absorption peak is at 978nm and the sub-peak value is at 919nm respectively, the main fluorescent peak is at 1018nm with the sub-peak value at 970nm. The integrated absorption cross section, stimulated emission cross section and fluorescent lifetime of Yb3+ were calculated theoretically. This result is useful to characteristic analysis of silicate laser glass. The comprehensive test results show that they can meet the application requirements of laser glass. |
