Abstract
Intrinsic bistability and hysteresis have been observed in the photoluminescence of bulk glass doped with Yb3+ and Tm3+ impurities at room temperature. Multiple instabilities also occur in channel waveguide lasers in this material. Consequently, local field effects exhibit more degrees of freedom than expected and have important implications for compact optical amplifiers and oscillators.
