Analytical approach to dynamics of reverse saturable absorbers
Journal of the Optical Society of America. B, Optical physics
We develop an analytical approach to the dynamics of band populations of reverse saturable absorbers modeled by the three-level approximation of the five-level rate equations. We find high-accuracy approximate solutions to these rate equations, taking into account the temporal shape of the incident laser pulse for different regimes of excitation. The results obtained are confirmed by direct numerical integration of the rate equations and are verified by solution of the full system of the ratedoi:10.1364/josab.17.001884 fatcat:yz4g5gjrdzdbtgcleoli2ia2bq
