Abstract

The effect of the types of alkaline earth metal ions (Mg2+, Ca2+ and Ba2+) and concentration of Al2O3 and BaO on the refractive index and the effective emission linewidths of the 4I13/2 - 4I15/2 transition of Er3+ ions in phosphate glasses, 64P2O5 · 12Al2O3 · 3.5(Er2O3 + La2O3) · 20.5MO (M = Mg, Ca, Ba) and 64P2O5 · 3.5(Er2O3 + La2O3) · (21.5 - x)Al2O3 · (11 + x)BaO (x = 0, 3.5, 6.5 and 9.5), were investigated. A single mode Er3+ doped phosphate glass fiber with a core diameter of 4 μm was fabricated by the rod-in-tube technique. A new Er3+ doped fiber amplifier is demonstrated pumping with a 980 nm fiber pigtailed-laser diode. A gain per unit length greater than 2 dB/cm is demonstrated, which is the largest gain per unit length for fiber amplifiers to our knowledge.
