Study on Thermal Stability and Spectroscopic Properties of Nd~(3+)-Doped Phosphate Laser Glasses

摘要

Fluorescence spectra, absorption spectra and thermal stability properties of Nd~(3+)-doped phosphate laser glasses were tested in this work. We calculated spectroscopic parameters of Nd~(3+)-doped phosphate laser glasses according to their absorption spectrum. Measuring and calculating linear thermal expansion coefficient, and analysising thermal stability of glasses show that this kind of Nd~(3+)-doped phosphate laser glasses has thermal expansion coefficient α = 38.75 x 10~(-7)/°C and optimal spectroscopic properties which extend application range of Nd~(+3)-doped phosphate laser glasses.
