Abstract
Modern mechanical engineering and instrument-making require extensive application of material processing innovation technologies, particularly laser processing. Chemical oxygen-iodine laser is accepted to be forward-looking. The essential constituent of the oxygen-iodine laser is the gas evacuation system under pressure of 10-1500 Pa. As the magnitude of the gas flow is tens of molar portions per second, there is no rational alternative to the cryogetter evacuation method with energy as well as overall dimension characteristics, especially when the matter concerns mobile laser systems. In this connection sorbent heat abstraction represent vital issue. This article is devoted to cryogetter evacuation process analyses under sorbent cooling by means of flat and finned cryo-panel.
