Fabrication and Spectroscopic Properties of Heavily Pr3+Doped Selenide Chalcogenide Glass and Fiber for Mid-infrared Fiber Laser
摘要
Abstract
In order to develop a high gain medium for fiber lasers operating at 3-5 μm waveband,0-0. 4％(in weight)Pr3+ions doped Ge12As20. 8Ga4Se63. 2 selenide chalcogenide glasses were prepared and the 0. 2％(in weight)Pr3+ions doped one was successfully drawn into step-index double-cladding fiber with the lowest loss of 2. 95 dB/m@6. 58μm by a multistage rod-in-tube method. The electron-probe measure microanalysis(EPMA),X-ray diffraction (XRD),differential scanning calorimeter(DSC),field emission transmission electron microscope(FE-TEM),trans-mission and mid-infrared fluorescence spectra were carried out to analyze the dispersion of Pr3+ ions in glass,the im-purity contents,thermal and optical changes caused by the Pr3+ ions'introduction. By analyzing the absorption and emission measurements of the serial glasses with the Judd-Ofelt theory,the Judd-Ofelt strength parameters,transi-tion probabilities,exited state lifetime,branching ratios,and emission cross-sections were also calculated. This sel-enide chalcogenide glass has high Pr3+ ions'solubility and emission characteristic,good thermal stability and fiber forming performance,indicating that it has potential to be used as mid-infrared laser working medium.关键词
