我们实现了基于掺铒光纤激光器泵浦的锗酸盐玻璃芯石英包层光纤的超连续谱光源。获得的光谱的长波长边缘位于2.7μm处。据我们所知，它是石英光纤的最长波长。测得平均输出功率高达 0.49 W。 1.6-2.7μm范围内的强度变化远小于十年。对不同长度的纤维进行了测试。 （(c) 2012 年，Astro Ltd.，由 WILEY-VCH Verlag GmbH & Co. KGaA 独家出版）（(c) 2011 年，Astro Ltd.，由 WILEY-VCH Verlag GmbH & Co. KGaA 独家出版）
We have realized supercontinuum source based on the silica-cladding fiber with the germanate-glass-core pumped by Q-switched Er-doped fiber laser. The long-wavelength edge of the spectrum obtained is located at 2.7 mu m. To our best knowledge it is the longest wavelength for the silica based fiber. Average output power as high as 0.49 W was measured. Intensity variation in the range of 1.6 2.7 mu m was much less than one decade. The fibers with different lengths were tested.
