| 摘 要： | We present theoretically a novel intrinsic optical bistability （IOB） in the Tm^3＋ /Yb^3＋ codoped system with a photon avalanche mechanism. Numerical simulations based on the rate equation model demonstrate distinct 10B hysteresis and critical slowing dynamics around the avalanche thresholds. Such an 10B characteristic in Tm^3＋ /Yb^3＋ eodoped crystal has potential applications in solid-state bistable optical displays and luminescence switchers in visible-infrared spectra.

| Abstract: | 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. |
