Resumen
Thermal lens spectrometry of thermo-optical properties of low silica calcium aluminate glasses doped with different concentration of neodymium dioxide was conducted. Thermal lens signal amplitude presented a linear dependence for neodymium concentrations up to 2.0 wt%, indicating that there was no fluorescence quenching. The quantitative treatment for the thermal lens effect also allowed determination of the absolute value of quantum efficiency, 0.87, for all samples. Thermal diffusivity is around 5.5 × 10-3 cm2/s with some dependence on Nd concentration. © 1997 Elsevier Science B.V. 219
