Dual-frequency shift leads to chaos and beating in an erbium-doped fiber laser [PDF]
We present a dual-frequency shift scheme to produce chaos and beating in an erbium-doped fiber laser while we give this laser physics model including a photo attenuator absorbing the photon, where the absorption frequency of the photo attenuator can be ...
