Erbium-doped fiber ring laser cavity in transient and steady states studied by a numerical approach

An erbium-doped fiber ring laser is modeled by use of the standard propagation and rate equations of a homogeneous, two-level medium. A numerical model is obtained by development of a spectral analysis of erbiumdoped fiber amplifiers. This approach is modified to account for the cyclical propagation...

Description
Summary:An erbium-doped fiber ring laser is modeled by use of the standard propagation and rate equations of a homogeneous, two-level medium. A numerical model is obtained by development of a spectral analysis of erbiumdoped fiber amplifiers. This approach is modified to account for the cyclical propagation of the field in the ring laser. Numerical simulations provide interesting information on the spectral behavior as well as important characteristics of the cavity, mainly the lasing wavelength and output power. The model also permits the study of competing modes' gain and signal evolutions during the transient state of the ring laser cavity. © 2000 Optical Society of America.
