采用提拉法生长了直径为15 mm的Ce 3+：LiCaAlF6（Ce：LiCAF）大晶体。由于其大尺寸，Ce：LiCAF晶体表现出来自Ce：LiCAF激光器的最大输出脉冲能量为21 mJ，波长为290 nm，吸收的泵浦能量为54 mJ，来自Q开关Nd：YAG激光器的四次谐波，以10 Hz的重复率操作。此外，激光阈值为12 mJ，斜率效率为39%。
A large Ce3+:LiCaAlF6 (Ce:LiCAF) crystal of 15 mm diameter was grown successfully by the Czochralski method. Owing to its large size, the Ce:LiCAF crystal demonstrated a maximum output pulse energy from the Ce:LiCAF laser of 21 mJ at a wavelength of 290 nm with an absorbed pump energy of 54 mJ from the fourth harmonic of a Q-switched Nd:YAG laser operated at a 10-Hz repetition rate. Furthermore, the lasing threshold was a low 12 mJ, and the slope efficiency was 39%.
