Abstract

A lead selenide quantum dot-doped fiber ring laser operating at 1.7 µm wavelength is proposed and investigated by numerical simulation for the first time. Its temporal and spectral characteristics under different simulation parameters are presented. The fact that the obtained temporal profiles using different simulation parameters are largely different is observed and analyzed. These results offer us a new practical path to generate a 1.7 µm continuous-wave and pulsed laser for deep biomedical application.
