高浓度Er3+掺杂硫系玻璃的中红外发光特性
Mid-infrared Emission Properties of Highly Er3+-doped Chalcogenide Glass
摘要
Abstract
Mid-infrared(MIR)lasers,owing to their high beam quality and super robustness,are widely used in fields from surgery,environmental monitoring,and material processing to laser radar.However,their development is greatly limited by the lack of optical gain materials with both high rare earth doping content and excellent mechani-cal resistibility.Here,highly Er3+-doped Ga2S3-La2S3-Na2S3 chalcogenide glasses(ChGs)up to 10%in Er2S3 concen-tration are obtained.The resulting glass shows high glass transition temperature(492℃)and large Vickers hardness(3.37 GPa),which is substantially greater than those of other ChGs.The intensity of 2.7 μm emission drastically increases with increasing Er3+content and reaches a maximum at 7.5%Er2S3.Moreover,the absorption and emis-sion cross-section at 2.7 μm are 10.6×10-21 cm2 and 15.7×10-21 cm2 at 7.5%Er2S3,respectively.The above research results provide a straightforward and effective strategy for the development of high gain rare earth doped MIR laser materials.关键词
