Yb∶YAP单晶光纤的生长及光谱性能研究
Growth and Spectral Properties of Yb∶YAP Crystal Fibers
摘要
Abstract
Yb3+-doped YAlO3(Yb∶YAP)crystal fibers with different doping concentrations were successfully grown using the micro-pulling-down method.X-ray diffraction(XRD)characterization verified their orthorhombic crystal structure.Absorption spectra,fluorescence spectra and fluorescence decay curves were systematically measured at room temperature.For the 2.00%(atomic fraction)doped sample,the absorption cross-section at 978 nm reaches 1.14×10-20 cm2,while the maximum emission cross-section at 1 000 nm is 1.39×10-20 cm2,showing good spectral compatibility with commercially available laser diodes.The measured 2F5/2 level lifetime for 0.25%,0.50%,1.00%,2.00%and 5.00%Yb∶YAP crystal fibers are 587,604,682,705 and 698 µs,respectively.These results collectively indicate that Yb∶YAP crystal fibers are promising gain media for ultrafast laser applications.关键词
