Abstract
The optical nonlinearity, saturation of the lower laser level, and spo ntaneous emission modify the relaxation oscillations in a Nd3+-doped f ibre laser. A novel four-level rate-equation model correctly describes the modified laser dynamics and allows the determination of the secon d-order susceptibility of the fibre, lifetimes of upper and lower lase r levels, cavity loss, and the number of oscillating modes by monitori ng relaxation oscillations. Measurements on five different Nd3+-doped fibres are reported.
