Theoretical study of the operation of gated saturable absorbers

Optical and Quantum Electronics, 1993
The operation of gated saturable absorbers is described by the classical space-time-dependent rate equation model considering both ground-state and excited-state absorption and stimulated emission. The effect of different molecular and cavity parameters on the transmitted pulse is shown.

Stabilization of solitonlike pulses with a slow saturable absorber

Optics Letters, 1995
We show that a soliton of the nonlinear Schrödinger equation perturbed by filter losses and/or the finite gain bandwidth of amplifiers can be kept stable by saturable absorbers with a relaxation time much longer than the width of the soliton. This provides for ultrashort pulse generation with a slow saturable absorber only and may have possible ...

Instabilities in a bimode CO2 laser with a saturable absorber

Optics Communications, 1990
We report on the observation of mode hopping in a bimode CO2 laser with a saturable absorber. When the control parameters are changed, the output intensity of this laser shows a succession of periodic regimes that may become completely erratic. Each of these regimes may be explained considering the role played alternatively by two unstable fixed points

LIGHT AMPLIFICATION IN SATURABLE ABSORBERS

Applied Physics Letters, 1968
It has been found that an absorber driven into saturation by a strong light pulse can amplify a weak light pulse simultaneously incident upon the medium. Gains as high as 20 cm−1 have been observed. This effect is believed to be related to the ability of a saturable absorber to bring about mode locking in a laser cavity.
