Abstract :
Summary form only given. Cerium-ion-doped crystals are already known as practical tunable ultraviolet laser media when pumped with the fourth harmonic of an Nd:YAG laser. A 60 mJ output from Ce:LiCAF has already been demonstrated with large Czochralski (CZ)-grown crystals (Marshall et al, 1994; Liu et al, 2001; Shimamura et al, 2000), and if other pumping schemes were available, it would expand the applicability of this laser medium. In this paper, we report finding new cerium ion excitation channels through Ce:LiCAF, Ce:LiSAF, and Ce:LiSCAF crystals, and find that they coincide completely with the transmission edge of each crystal.
