摘要

由于在军事和民生领域重要的应用潜力，~3 μm激光光源的开发一直以来受到了极大关注。传统中红外激光玻璃因其较高的声子能量会极大削弱发光离子的辐射跃迁几率，导致无法获得有效激光输出。因此，寻找高效且稳定的中红外~3 μm激光增益材料具有重要价值和研究意义。本文报道了在氟硅酸盐玻璃中SiO

Abstract

Mid-infrared lasers operating at around 3 μm have been paid much attention due to their significant potential at civil and military field. Traditional mid-infrared laser glass matrix presents high phonon energy

which causes the radiative transition probability of luminescent ions being greatly weakened

and thus leads to the inability to obtain effective laser output. Therefore

it is of great value to explore efficient and stable gain materials for 3 μm laser. In this paper

we report the

fluorosilicate glass matrix. The obtained glass ceramic can maintain more than 80% transmittance. The nanocrystal species and elemental distribution in the glass were characterized by X-ray diffractometry(XRD) and transmission electron microscopy(TEM) technology. Under 980 nm laser diode(LD) excitation

the mid-infrared emission at 2.7 μm of Er

for the heat-treated sample is greatly enhanced

which is about 19 times stronger than that of the precursor sample. The related mechanism for the luminescence enhancement is further explained by the results of absorption spectra and steady state fluorescence spectra. The present results may provide reference data and research ideas for the development of ~3 μm laser gain materials.
