An excitation migration over the level 411~/2 was studied in Cr:Er:YSGG laser crystal using an upconversion nonholographic light induced grating (LIG) technique. A long distance of migration ( = 1 /zm) was found. The diffusion coefficient was determined to be equal to 7 Γ— 10 -7 cm2/s. This value was

## Abstract ## Background and Objective If there is insufficient bonding to the enamel, the shrinkage of composites that occurs during polymerization can result in a gap between the filling material and the cavity wall. This gap permits the passage of bacteria or their metabolic products and also
