摘要：

A crystal growth method for growing UV grade CaF2 crystals from fluorspar has being developed using purified Bulgarian fluorspar mixed with 2% PbF2. Excimer laser damage characteristics of the grown crystals were performed in a specially designed laboratory system into a high pressure camera. It was found that the fluorine mixture does not change, neither on the outer surface of the crystals nor in the bulk even after 3500 h of contact, no color centers were observed on the windows of the XeCl laser and that there are no remarkable differences between the surface and the bulk damage thresholds. Thus, the grown crystals of CaF2 are suitable for manufacturing windows for excimer lasers and for other optical elements used in UV and vacuum UV spectra regions.
