Abstract

Near-infrared luminescence properties of Nd and Ho ions in barium gallo-germanate glasses have been reported. Several spectroscopic parameters for Nd and Ho ions have been determined from the Judd-Ofelt analysis and absorption/luminescence measurements. Quite large luminescence lifetime, quantum efficiency and stimulated emission cross-section have been obtained for the main F → I (Nd) and I → I (Ho) laser transitions of rare earths in barium gallo-germanate glasses. It suggests that barium gallo-germanate glass is promising for near-infrared laser application at emission wavelengths 1064 nm (Nd) and 2020 nm (Ho).

摘要

报道了掺钕和掺钬钡镓锗酸盐玻璃的近红外荧光性能。通过 Judd-Ofelt 分析和吸收/荧光测量，确定了钕和钬离子的几个光谱参数。从钡镓锗酸盐玻璃中稀土元素的主要 F → I（Nd）和 I → I（Ho）激光跃迁得到了相当大的荧光寿命、量子效率和受激发射截面。这表明钡镓锗酸盐玻璃有望在发射波长为 1064nm（Nd）和 2020nm（Ho）的近红外激光应用中得到应用。
