We report experimental results on a highly efficient optical limiter that uses a three-mirror, multipass ring configuration. The optical limiter's enhanced performance is based on the accumulative effect that is achieved when the laser beam passes through the sample several consecutive times. Its feasibility was demonstrated for media with different limiting action processes, namely, reverse sa...

A high-quality peak limiting amplifier is described which uses a p-channel field-effect transistor as the variable gain element.

Chaos control by simple limiters is an easy-to-implement and effective method of stabilizing irregular fluctuations. Here we show that applying limiter control to a state variable can significantly shift its mean value. In many situations, this is a countereffective as well as unexpected result, when the aim of control is also to restrict the dynamics. We discuss this effect on the basis of a m...

Optical limiters are nonlinear devices that feature decreasing transmittance with increasing incident optical intensity, and thus can protect sensitive components from high-intensity illumination. The ideal limiter reflects rather than absorbs light in its active (“limiting”) state, minimizing risk of damage to the itself. Previous efforts realize reflective (rather absorbing) were based on emb...

In this paper, the nonlinear optical response of thermo-optic origin exhibited by series of Fuchsin dyes at low continous wave laser powers is studied in liquid and solid media and optical limiter action based on nonlinear refraction isdemonstrated.

In our earlier paper [l]f expressions for the spectrum of an FM wave received in the presence of random (fluctuation) noise were obtained in the two extreme cases of no limiting and "super"-limiting.** It is the purpose here to develop the completelygeneral theory for the demodulated wave, taking into account the effects of arbitrary amounts of limiting on the noise and signal spectra and power...
