摘要：

The amplification properties of a highly Er3+-doped phosphate fiber were measured. Gain was observed in the wavelength region of 1.525-1.57-mu-m and the wavelength at maximum gain was 1.535-mu-m. Since the absorbed pump threshold obtained experimentally agreed with the calculated result, no cooperative upconversion process occurred in the 1.53 wt% Er2O3 fiber.
