Abstract
We have analyzed the characteristics of 1.3 μm praseodymium (Pr3+) doped bidirectionally pumped double pass (BIP-DP) configuration amplified spontaneous emission (ASE) source theoretically and experimentally. The source’s simulation model was established and corresponding simulated results were given. The effects of pump ratio, Pr3+-doped fiber (PDF) length, total pump power and source’s optical losses were researched. The output power of BIP-DP ASE source is mainly affected by the total pump power, PDF length and source’s optical losses, while it has little relationship with the pump ratio. The BIP-DP ASE source operating at the symmetric bi-directional pump condition was constructed experimentally. The acquired output power of more than 5 mW has been obtained experimentally, which was with the quasi-gaussian output spectrum, and its 3 dB bandwidth is ~ 20 nm.
