Local structure investigation of Cr3+ doped KTP single crystals
Abstract
Using superposition model (SPM), the crystal field (CF) parameters and zero field splitting (ZFS) parameters of Cr3+ doped KTP single crystals are determined The possible sites for Cr3+ ions in KTP with distortion are taken up for calculation. Considering local distortion the theoretical ZFS parameters are in good agreement with the experimental values. The optical energy values for Cr3+ in KTP are calculated with the help of CF parameters and CFA program. The results show that Cr3+ ions substitute at Ti4+ (2) sites in KTP single crystals.
