Abstract
High resolution FTIR spectroscopy is applied at 9—300 K to KTiOPO4 single crystals doped with Er or W. The vibrational transitions due to the impurity-OH defect interaction have been detected and studied. By means of polarized absorption measurements in KTP:W the orientation of the OH dipole along the Ti-O-Ti chains has been established with the presence of tetravalent tungsten at the Ti2 site. Thermally induced line-broadening and shifts are also reported and analyzed according to the single phonon coupling model.
