Abstract
In this paper, we report the optical and thermal properties of a new Nd-doped phosphate laser glass. Glass samples with 0.5-3.7 wt% Nd-doping concentrations were prepared, annealed, cut and polished for different measurements, including glass density and refractive index, absorption spectra and emission cross section, as well as laser properties. A Mach- Zehnder interferometer was used to measure the temperature coefficient of refractive index (dn/dT) and optical path length (dS/dT) in the temperature range of 30-100 °C. Moreover, by increasing the glass temperature up to 500 °C, the thermal expansion of this new glass was also measured. On the basis of these optical, thermal and thermo-optic parameters, we calculated and analyzed some of glass parameters, such as the electronic polarizability of oxygen ions, the optical basicity of this phosphate-based glass, and especially discussed their thermal shock resistance properties. It is suggested that this new Nd-doped phosphate laser glass is an excellent candidate for high energy and high repetition rate laser applications.
