The laser behavior of a centimeter-scale codoped silica fiber with core numerical aperture and core diameter of 0.15 and 8 μm, respectively, is reported. The core glass was prepared by the sol–gel method combined with high-temperature sintering; it contained ion concentration as high as and an Al/Er mole ratio of 10. The high doping homogeneity of ions in the fiber core was confirmed by an electron probe microanalyzer element scanning, long emission lifetime of 11.4 ms, and low refractive index fluctuation of fiber core (). The signal gain of fibers with 4.6 cm, 10 cm, and 16 cm lengths was tested in the 1500–1620 nm range. A gain of 7 dB is achieved at 1560 nm in a 16-cm-long EDF under 230 mW pump power. Aimed for sensor application, the laser behavior of Er/Al codoped fiber was tested at 1572 nm. A slope efficiency of 12% and an output power of 15 mW were achieved in a 10-cm-long fiber under 166 mW absorbed pump power. The newly developed silica fiber is promising for use in high-repetition-rate lasers.
