Abstract

Whispering gallery mode (WGM) lasers at ∼2µ are demonstrated in PbO--- (PBG) heavy metal oxyfluoride glass microspheres. A 793 nm diode laser is used to pump the PBG microsphere and achieve single-mode and multimode WGM lasing. The fluorescence spectra of -doped PBG glasses are measured under 793 nm diode laser pumping. The maximum absorption and emission cross sections of :→ are calculated to be 8.23×10 and 4.42×10, respectively. The experimental results indicate that these PBG glass microspheres could become an important photonic component for infrared laser applications.

摘要

在PbO---（PBG）重金属氟氧化物玻璃微球中展示了波长约为2µ的回音壁模式（WGM）激光器。使用793nm二极管激光器泵浦PBG微球，实现了单模和多模WGM激光发射。在793nm二极管激光器泵浦下测量了掺杂PBG玻璃的荧光光谱。计算出:→的最大吸收和发射截面分别为8.23×10和4.42×10。实验结果表明，这些PBG玻璃微球可能成为红外激光应用的重要光子组件。
