Abstract Photoexcited defect clusters in the bulk of KH{sub 2}PO{sub 4} crystals are investigated using a microscopic fluorescence imaging system with 1 {mu}m spatial resolution. The observed defect cluster concentration is approximately 10{sup 4}{endash}10{sup 6}&hthinsp;per&hthinsp;mm{sup 3} depending on the crystal growth method and sector of the crystal. The intensity of the emission clusters varies widely within the image field while a nearly uniformly distributed background is present. Spectroscopic measurements provided information on the emission characteristics of the observed defect population. {copyright} {ital 1999 American Institute of Physics.}
