Abstract
A detailed investigation on thermal and spectroscopic properties of different Ho3+/Yb3+ concentration ratios in silica-germanate glasses is displayed. According to the measurement of thermal properties, the host glass possesses high transition temperature (585 °C) as well as the large ÎT(155 °C). The 2.0 μm fluorescence can be obtained from all the samples. Maximum stimulated emission cross-section of around 2.0 μm is 0.56 Ã 10â20 cm2 of Ho3+ as calculated by McCumber theory. Besides, the underlying mechanism is analyzed by means of fluorescence spectra. Thus, desirable thermal properties and spectroscopic characteristics of Ho3+/Yb3+ co-doped silica-germanate glass is a promising material in 2.0 μm emission.
