Abstract

An approximate model, along with the experimental verification for thulium (Tm)-doped silica glass fiber amplifier at 1470 nm upon 1064-nm pumping, has been proposed to estimate the optimum parameters and to analyze its performance in terms of gain, bandwidth, and noise performance. The Tm-doped silica glass fiber amplifier was found to be suitable for wavelength division multiplexing application, although a high pump power of more than 1000 mW was needed to achieve a significant gain.
