PROCESS OF MANUFACTURE OF CATHODE FOR CO LASER Russian patent published in 1995 - IPC

FIELD: quantum electronics. SUBSTANCE: process of manufacture of cathode for CO₂ laser consists in mixing of powder of copper and copper oxide, in its formation by pressing and baking by heating in oxygen-containing atmosphere at temperature 280-300 C for the course of 25-30 min. Catalytic matter based on palladium and silver is applied to outer nonworking surface of cathode, is dried at temperature 100-120 C for the course of 100-150 min and sintering of catalytic matter is conducted by heating of cathode at temperature 530-550 C for the course of 15-20 min. Thus manufactured cathode has porous structure which provides for larger surface of catalytic coat based on palladium and silver and for interaction of molecules of CO and O₂ on this surface which considerably enhanced regeneration rate of CO₂. EFFECT: enhanced regeneration rate of CO₂. 2 cl, 3 dwg
