Optical limiting via spontaneously generated coherence [PDF]
Scientific Reports, 2023 We investigate the reverse saturable absorption (RSA) and optical limiting (OL) in a three-level V-type quantum system considering the effect of the spontaneously generated coherence (SGC). It is shown that in the absence of the SGC effect, the saturable
