We investigated optical bistability (OB) and optical multistability (OM) behavior in a 35 nm solid Er3+: YAG crystal with a four-level system proposed for an atomic medium inside a unidirectional ring cavity. It is found that the intensity and frequency detuning of the signal and coupling fields as well as Er3+ concentration can influence the OB and OM behavior.
