BERNHARDI, E.H. et al. A single-element plane-wave solid-state laser rate equation model. S. Afr. j. sci. [online]. 2008, vol.104, n.9-10, pp.389-393. ISSN 1996-7489.
A numerical rate equation model has been developed to describe the dynamics of a solid-state laser during continuous wave or Q-switched operation. The model allows the optimization of parameters such as the output coupler transmission percentage, crystal length and beam diameters, with the aim of improving the laser output performance. To validate the model, it was applied to a Nd:YLF laser, and proved successful in predicting and explaining the laser dynamics. It also satisfied our objective of creating a useful laser design tool.
