Abstract :
The magnetic and optical properties of two types of hole centers formed in KDP (KH2PO4) under irradiation and variation of their concentration at thermal, laser and radiation annealing of crystals have been investigated by means of ESR and optical spectroscopy methods. It has been found that wide bands of optical absorption in the UV region of the spectrum with the maximum near 268 nm belong to these centers.
