Crystal growth of Ce : LiLuF4 for optical applications
High-quality Ce:LiLuF4 (Ce:LLF) crystals were grown by the Czochralski technique using CF4 as reactive atmosphere. The segregation coefficient of Ce3+ was determined to be 0.066 (3). No changes in the lattice parameters due to the presence of the Ce3+ in the lattice were observed. Laser action in the ultraviolet region was obtained by pumping this active medium with a KrF excimer laser in 248 nm.
