A short Bi doped fiber laser operating in the wavelength region of 1160-1179 nm has been demonstrated. The influence of unsaturable loss on laser performance is investigated. Excited state absorption in Bi doped germano-alumino silicate fiber is reported in the 900-1300 nm wavelength range under 800 and 1047 nm pumping. Bi luminescence and fluorescence decay properties under different pumping wavelengths are also investigated.
已展示出一种工作在1160 - 1179纳米波长区域的短掺铋光纤激光器。研究了非饱和损耗对激光性能的影响。报道了在800纳米和1047纳米泵浦下，掺铋锗铝硅酸盐光纤在900 - 1300纳米波长范围内的激发态吸收。还研究了不同泵浦波长下铋的发光和荧光衰减特性。
