Growth, spectroscopic and laser properties of heavily doped LiCaAlF 6 :Ce 3+

The aim of this work is growth of LiCaAlF 6 :Ce 3+ crystals by Bridgman technique and study of spectroscopic and laser characteristics. The maximum absorption coefficient of Ce 3+ ions appeared to be up to 7 cm -1 and maximum of slope efficiency of laser action as high as 47% was achieved. Conclusions about interaction and distribution of cerium impurity centers are also discussed.
