摘要/Abstract

摘要： The modeling of rare-earth-doped fiber amplifier is accomplished by utilizing the rate and propagation equations of distinct levels for a laser medium. A complex theoretical model for neodymium (Nd3+), erbium (Er3+), thulium (Tm3+) and ytterbium (Yb3+) codoped telluride glass fiber covering 0.4|2.0 μm emission spectra is presented. The emission spectra of Nd3+-Er3+-Tm3+-Yb3+ codoped telluride fiber are realized with the excitation of both 808 and 980nm lasers pumped at 500mW. Numerical methods are used to calculate the emission spectra covering 0.4|2.0 μm. With the Nd3+, Tm3+ and Yb3+ ion concentrations fixed at 2 ￡ 1020 ion/m3, the Er3+ ion concentration optimized to 8 ￡ 1020 ion/m3 and the ˉber length spanning from 0.5 to 2 m, a peak amplified spontaneous emission (ASE) power of 19.8mW is attainable, and a minimum ASE power of 7.96mW can also be achieved. The analytical techniques and results indicate that when a telluride codoped fiber with suitable ion concentrations of Nd3+, Er3+, Tm3+ and Yb3+ is excited by both 980 and 808nm pump lasers, 0.4|2.0 μm emission spectra are attainable for vast optical applications.
