In this article, a technology of sandwich-like structures division is offered. As a technological instrument, this technology combines the use of radiation of a solid-state laser on yttrium aluminum garnet (YAG) with the wavelength 1.06 µm, whose intensity is allocated in the depth of the ceramic-metal, in accordance with the law of Buger-Lambert-Berr, and the use of radiation of a CO2-laser with the wavelength 10.6 µm, for which the ceramic-metal is not transparent.

PL

W artykule proponowana jest technologia podziału struktur sandwichowych. Jako instrument technologiczny, technologia ta łączy wykorzystanie promieniowania laserem stałym granatu itrowo-aluminiowego (YAG), przy długości fali 1.06 µm, którego natężenie zlokalizowane jest w głębi spieku ceramicznego, zgodnie z prawem Lamberta-Berra oraz zastosowanie promieniowania laserem CO2 o długości fali 10.6 µm, dla którego spiek metaliczny nie jest przezroczysty.
