On two models of light pulse delay in saturable absorber [PDF]
, 2010 A comparative analysis of two approaches to description of the light modulation pulse delay in a saturable absorber is presented. According to the simplest model, the delay of the optical pulse is a result of distortion of its shape due to absorption ...

Controlled Generation of Bright or Dark Solitons in a Fiber Laser by Intracavity Nonlinear Absorber
IEEE Photonics Journal, 2016 We numerically found that an intracavity nonlinear absorber (saturable absorber or reversed saturable absorber) plays a crucial role in the formation of dissipative bright or dark solitons in a fiber laser. The operation of an all-normal-dispersion fiber
