โœฆ Synopsis

An erbium-doped fiber ring laser is modeled, using the standard propagation and rate equations of a homogeneous, two-level medium. The numerical model has been obtained by developing a spectral analysis of erbium-doped fiber amplifiers. This approach is modified to account for the cyclical propagation of the field in the ring laser. The 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 evolution during the transient state of a ring laser cavity, which enables cavity lasing wavelength predictions. To our knowledge, this study is the first of its kind. แฎŠ 2000

The central wavelength of the incident pulsed-laser beam is 0.8 m, and the corresponding circular frequency is 0 2.35455 = 10 15 radrs. We define โŒฌ as the full width at half maximum of the incident pulse, and z as the Talbot distance t of the central frequency light. First, we will calculate the int

## Abstract We have successfully generated the mutisoliton pulses using a Gaussian pulse in a fiber optic ring resonator incorporating an erbiumโ€doped fiber (EDF) and a semiconductor optical amplifiers (SOAs). The multisoliton memory time within the system is also measured. Initially, the Gaussian
