摘要：

Characteristics of pulsed X-ray induced transient absorption at 1061 mn have been determined for LiNbO3, TiO2:LiNbO3, and MgO:LiNbO3. The addition of the dopants TiO2 and MgO reduces the induced absorption significantly, The two materials, LiNbO3 and TiO2:LiNbO3, decay with an approximate 1/t(1/4) time dependence for the time interval 0.01 to 8 ms. After 8 ms, the decay rate for LiNbO3 is faster than 1/t(1/4), and the decay rate for TiO2:LiNbO3 is slower than that initial rate. A low-intensity absorption which lasts for about 20 mu s is observed for the MgO:LiNbO3. Peak radiation-induced absorption coefficients for LiNbO3, TiO2:LiNbO3, and MgO:LiNbO3 have been determined.
