Neodymium-doped phosphate laser glasses are the laser glass materials which were developed relatively early,and used in the fields such as nuclear fusion, high power laser amplifier and optic fiber laser and so on in China. But we are in trouble all the time,because the high thermal expansion coefficient leads to bad thermal and chemical stabilities and low-heat mechanical intensities. The thermal stability is very important to laser glasses and it is emphasis point in my work. By changing the composition of glass such as adding Al_2O_3,the thermal expansion coefficient of the sample dramatically decreases,and the thermal expansion coefficient of the glasses in this work achieves α=38.75×10~(-7)/ ℃. Transition temperature T_f and softening temperature T_g of the glasses are 684 ℃ and 605.5 ℃ respectively. Introducing of F_2 in glasses and improving preparation technology not only can get rid of Pt and water molecular, but also decrease phonon energy of glasses, at the same time, improve phonon efficiency and optimize spectroscopic properties. Fluorescence and absorption spectra and thermal expansion coefficient of Nd~(3+)-doped phosphate laser glasses are tested at room temperature. Spectroscopic parameters of Nd~(3+)-doped phosphate laser glasses were calculated according to their (absorption) spectrum. The transitions of Nd~(3+)from ~4F_(3/2) to ~4I_(11/2) and from ~4F_(3/2) to ~4I_(13/2) are corresponding to (fluorescence) wavelength 1 056 and 1 321 nm respectively under the excitation of 514 nm argon ions laser at room temperature. Generally, quantum efficiency of energy level transition are determined by the phonon energy of substrate to large extent. The more phonon energy,the stronger multi-phonon non-radiation relaxation, so the smaller quantum efficiency is corresponding to the weaker fluorescence intensity. To decrease phonon energy of glass substrate, introducing F_2 in glasses can improve phonon efficiency and enlarge bandwidth of fluorescence spectral line. All the researches extend the application range of neodymium-doped phosphate laser glasses.

掺钕激光玻璃广泛应用于核聚变、高功率激光放大器和光纤激光器等领域。磷酸盐玻璃热膨胀系数高、热稳定性和化学稳定性差、热机械强度低。通过改变玻璃组分,即添加Al2O3和F2,并改进制备工艺来降低热膨胀系数,除去铂和分子水。测量了磷酸盐玻璃中Nd3+离子的荧光光谱、吸收光谱及玻璃的热膨胀系数。根据吸收光谱计算掺钕磷酸盐激光玻璃的光谱参数。通过对掺钕磷酸盐玻璃的热膨胀系数的实际测量和计算,分析了玻璃的热稳定性。结果表明,在基质玻璃中引入Al2O3使激光玻璃的热膨胀系数可降低到α=38.75×10-7/℃,引入F2既达到了除水的目的又降低了玻璃的声子能量,提高了荧光发射的量子效率,并优化了光谱性能,拓展了掺钕磷酸盐激光玻璃的应用范围。
