Abstract :
We derive and compute a model to describe the spectral dynamic behavior of quasi-three-level laser resonators operated in gain-switched conditions. This model, based on rate equations, predicts both intensity and spectrum evolutions of the laser output. It is specifically applied to a Yb:YAG laser resonator, and the effects of intracavity losses on the emitted wavelength are also investigated. The phenomena forecasted by our model are in very good agreement with our experiments
