The presence of defect clusters in the bulk of large KH2PO4 (KDP) crystals is investigated using a spectral imaging technique and a microscopic optical system allowing for 1 micron spatial resolution. The observed particle concentration varies between 104-106 per mm3 depending on the crystal growth method and sector of the crystal. Exposure in high power 355 nm, 3 ns laser irradiation leads to a significant reduction of the number of observed defect centers.
