Publikováno v: 2021 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS).

In this paper, comparison between absolute orientation determination methods of doubly rotated blanks is given. To measure doubly rotated cut, classical goniometers need several manipulations of the blanks (for example 90° shift rotation) and they a

Defects that are formed during crystal growth pose a serious obstacle for potential application of La 3 Ga 5.5 Ta 0.5 O 14 (LGT) as a laser or piezoelectric crystal. We have performed the study of the defects origin in LGT crystals grown in different
