The effects of temperature on the spectra and output power of thulium-doped fiber lasers (TDFLs), pumped at 1567 nm and emitting around 1950 nm were studied using a model based on steady-state rate equations, incorporating the temperature dependence of thulium cross sections. Numerical simulations show that with a temperature variation from 173 to 373K, the central wavelengths of the output spectra evolve from 1860 to 1910 nm. At the same time, output power and slope efficiency decrease with increasing temperature.

摘要

The effects of temperature on the spectra and output power of thulium-doped fiber lasers (TDFLs), pumped at 1567 nm and emitting around 1950 nm were studied using a model based on steady-state rate equations, incorporating the temperature dependence of thulium cross sections. Numerical simulations show that with a temperature variation from 173 to 373K, the central wavelengths of the output spectra evolve from 1860 to 1910 nm. At the same time, output power and slope efficiency decrease with increasing temperature.
