Analytical treatment for the study of an erbium-doped fiber ring laser fed by a sinusoidally modulated pump power

摘要: An analytical procedure is employed to account for the response of an erbium-doped fiber ring laser whose pump power sinusoidally modulated. The approximations considered, only strictly valid very low modulation indexes (of order some hundredths), reveal origin relationships between resonances main harmonics present in response. However, both experimental and numerical results show how qualitative conclusions concerning are also much higher than ones corresponding approximation validity range.
