dc.description.abstractThe performance and efficiency of a praseodymium-doped La-Ga-S chalcogenide glass fibre 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 fibre and experimentally obtained emission and absorption cross sections. The model has been used to optimize the fibre 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 fibre amplifier for a pump power of 200 mW in contrast to 18. 8dB for the same pump power in the Pr3+-doped fluoride fibre amplifier.en
