BRIEF COMMUNICATIONS: Corrosive activity of sodium nitrite solutions used in lasers
An investigation was made of the corrosion of the materials used in systems for circulating a liquid solution of sodium nitrite, which is applied as a light filter in lasers. It was found that such a filter was unsuitable for prolonged use in laser systems because of its corrosive effect on the majority of construction materials, and because it could not be used at temperatures below 0?C.
