| 摘要: | 报道了一种可用于2μm商用激光器有效激发的中红外宽带发光玻璃. 采用真空熔融淬冷法制备了Pr3+掺杂硒基玻璃的系列样品, 测试了样品的吸收光谱以及2μm激光泵浦下的3~5μm中红外荧光光谱, 观察到了由激发态吸收造成的近红外荧光. 通过Judd-Ofelt理论计算了不同浓度Pr3+离子掺杂玻璃样品的强度参数Ωt (t=2, 4, 6)、辐射寿命和受激发射截面等光谱参数, 讨论Pr3+离子局域配位环境对发光特性的影响. 结果表明, 4.6μm和4.8μm对应的跃迁能级具有较好的发光特性, 相比其他体系玻璃具有更大的受激发射截面, 是一种理想的中红外激光基质材料. |
| Abstract: | A series of Pr3+-doped selenide glasses are prepared by melt-quenching method. Absorption spectra and intense mid-infrared (3~5μm) fluorescence spectra have been measured with different concentration Pr3+ doped selenide glasses using the pump of 2.0μm. Besides, near-infrared (1.0~1.8μm) emission spectra can be detected due to the excited state absorption of Pr3+ when pumped by 2.0μm. According to the Judd-Ofelt theory, the intensity parameters Ωt (t=2, 4, 6), radiative lifetimes and stimulated emission cross-section of different concentration Pr3+ doped selenide glass are calculated, and the influence of coordination environment of Pr3+ on the luminescence property are addressed. The results indicate that the energy level transition corresponding to 4.6μm and 4.8μm possesses the larger stimulated emission cross-section, as such this system has the potential to be a good gain material for mid-infrared fiber laser. |
