CALCIUM FLUORIDE OPTICS WITH IMPROVED LASER DURABILITY

摘要

The present invention relates to an improved calcium flow which may be used in the transmission of electromagnetic radiation of less than 200nm fluoride single crystal optical body. The optical body is CaF as the main component and, in one aspect, 0.1 ~ 200 ppm of Mg, 0.1 ~ 200 ppm of Sr, 0.1 ~ 200 ppm of Ba, 0.5 ppm of Ce, and ; comprises at least one dopant / Mn selected from the amount of 0.5 ppm. ; CaF , laser, dopants, coat, durability
