防眩玻璃的研制

一、防眩玻璃配方的确定 配方的确定主要考虑两个方面的因素,其一是玻璃的光谱性质,使玻璃在紫外波段(200～300nm)和红外波段(800～1100nm)均有较大的吸收,可见光波段的透过率必须大于50％;其二应使玻璃具有优良的物理化学性能。根据上述要求,本实验采用了三个系统的玻璃配方进行了实验(表1)。     

Optimization of spectroscopic properties of ytterbium-doped laser glasses

Four laser glasses with high emission cross sections are experimentally obtained. The laser performance parameters are determined from the spectroscopic parameters of these glasses and compared with those of developing laser glasses abroad. It is shown that Yb~(3-)-doped telluorogermanate, Yb~(3 )-doped niobosilicate glasses have the highest emission cross section and gain coefficient, the smallest minimum pumping intensity and saturation pumping intensity, and the lowest minimum fraction of excited ions. Yb~(3 )-doped borate glass follows just behind them. These glasses have some spectroscopic advantages over laser glasses developed recently elsewhere. Yb~(3 )-doped phosphate glass is comparable to phosphate laser glass which had high emission cross section and was developed recently by HOYA Corporation in Japan.The domestic glasses with optimum spectroscopic properties may be promising candidates for applications in high-average power and high-peak power solid state lasers, especially laser for the ne
