Nonlinear Dependence of Response Rateon Intensity in Doped KNSBN Crystals
摘要
Abstract
Nonlinear dependence of the response rate on light intensity (τ-1∝Ix,x≠1) is obtained in doped KNSBN crystals. One of them has a superlinear intensity-dependent response rate which cannot be explained by previous model. Another anomalous phenomena are that the power coefficient x is near]y equal to 1 while the density of filled shallow trap is higher in reduced Co:KNSBN crystal. A new model of two types of carriers with multiple trape is proposed to explain the anomalous phenomena.
