Development and saturation investigation of MALO saturable absorber
Przeglad Elektrotechniczny, 2014 The paper describes the investigation of saturation effect in newly developed MgAl2O4:Co saturable absorber with the aim of thermally bounding it with the active media such as erbium glasses. On the basis of the experimental results the most important parameters, from the point of view of laser generation, such as ground state absorption cross section,

Slow light in saturable absorbers [PDF]
Physical Review A, 2008 In connection with the experiments recently achieved on doped crystals, biological samples, doped optical fibers and semiconductor heterostructures, we revisit the theory of the propagation of a pulse-modulated light in a saturable absorber. Explicit analytical expressions of the transmitted pulse are obtained, enabling us to determine the parameters ...
