In view of a responsible destination and hard operation conditions strong technical requirements are made to glass ele-ments of a thermo-optical coating for spacecraft radiators where a basic requirement of them is absence of chips and micro-cracks. There are carried out investigations of the influence of laser radiation parameters upon end face quality in the in glass element obtained through the method of controlled thermo-splitting. A quality considerable increase is shown in the surfaces of division at the use of the method of the end-to-end laser controlled thermo-splitting in comparison with the methods of part-through laser controlled thermo-splitting and scribing with a diamond cutter with the further after-break.
