摘要:
摘要： In this work, we investigate the 1550-nm fluorescence efficiency and heat generation of the erbium-doped fiber (EDF) pumped in the 800 nm band by pulsed (mode-locked) and quasi-continuous-wave (non-mode-locked) Ti:sapphire lasers. The result shows that the 1550-nm fluorescence power generated by a non-mode-locked laser (NMLL) can be doubled as much as that generated by a mode-locked laser (MLL). Comparing EDF pump by NMLL with EDF pumped by MLL, MLL can produce higher temperature in EDF core. The increased temperature is beneficial to reduce the radiation-induced absorption of gamma-ray irradiated EDF. Therefore, it may be possible to construct an anti-irradiated superfluorescence fiber source for aerospace navigation by switching between NMLL and MLL modes. 出版者： Issy-les-Moulineaux: Elsevier Masson SAS 出版日期： 2014-12-01 出處： Aerospace science and technology, 2014-12, Vol.39, p.187-189 版權： 2014 Elsevier Masson SAS 版權： 2015 INIST-CNRS 識別號： ISSN: 1270-9638 識別號： EISSN: 1626-3219 識別號： DOI: 10.1016/j.ast.2014.08.014
