We present theoretically a novel intrinsic optical bistability (IOB) in the Tm3+/Yb3+ codoped system with a photon avalanche mechanism.Numerical simulations based on the rate equation model demonstrate distinct IOB hysteresis and critical slowing dynamics around the avalanche thresholds.Such an IOB characteristic in Tm3+/Yb3+ codoped crystal has potential applications in solid-state bistable optical displays and luminescence switchers in visible-infrared spectra.
