Thermal lens in magneto-active fluoride crystals
Source abstract
Abstract
Abstract The thermal lens magneto-active CeF3, KTb3F10 and Na0.37Tb0.63F2.26 fluorides was investigated by the phase-shift interferometry technique. It was shown that the fluorides introduce a much weaker thermal lens into the laser beam than a traditional TGG crystal. The advantage is 3, 20, and 6 times for CeF3, KTb3F10 and Na0.37Tb0.63F2.26, respectively, with allowance for the need to increase length for achieving the same angle of rotation of the polarization plane because of the smaller Verdet constant. The measurement results were used to calculate the focal shift and the thermo-optical parameter αP/κ for the studied materials.
