Abstract
We introduce a new approach for generating and tuning optical limiting behavior that relies exclusively on a static magnetic field, eliminating the requirement for n laser fields. We investigate the effect of an external magnetic field on induced reverse saturable absorption (RSA) and optical limiting (OL) in a V-type quantum system configuration in the D-line of 
atoms. We show that Zeeman splitting induced by the static magnetic field can generate and tune the characteristics of the optical limiting, i.e., limiting threshold and efficiency. Furthermore, this approach enables control across a broad spectral range—from microwave to visible frequencies—depending on whether normal or anomalous Zeeman splitting is used. It is shown that the Doppler broadening plays a destructive role in establishing the OL. The proposed mechanism provides a tunable and easily implementable strategy for developing active optical limiters suitable for optical protection and integrated photonic applications.
