Abstract

The performance and efficiency of a praseodymium-doped La-Ga-S chalcogenide glass fiber amplifier have been analyzed using a comprehensive large-signal numerical model. The four level laser model incorporates the LP₀₁ mode radial field distribution in step-index single- mode fiber and experimentally obtained emission and absorption cross sections. The model has been used to optimize the fiber parameters for small-signal operation. The optimum cut-off wavelength of the LP₁₁ mode has been found to be 700 nm. It follows from the analysis that at 1310 nm a small-signal gain of 36.7 dB can be expected from the Pr³⁺-doped chalcogenide fiber amplifier for a pump power of 200 mW in contrast to 18.8 dB for the same pump power in the Pr³⁺-doped fluoride fiber amplifier.
