Abstract
Characteristics of pulsed X-ray induced transient absorption at 1061 mm 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 TiO 2:LiNbO3, decay with an approximate 1/t1/4 time dependence for the time interval 0.01 to 8 ms. After 8 ms, the decay rate for LiNbO3 is faster than 1/t1/4, and the decay rate for TiO2:LiNbO3 is slower than that initial rate. A low-intensity absorption which lasts for about 20 μs is observed for the MgO:LiNbO3. Peak radiation induced absorption coefficients for LiNbO3, TiO2:LiNbO3, and MgO:LiNbO3 have been determined
