An investigation was made of the lasing properties of Q-switched YAG:Er/sup 3 +/ crystals (/sup 4/I/sub 11/2/--/sup 4/I/sub 13/2/). An energy of 100 mJ was obtained in the TEM/sub 00/ mode and the pulse duration was 65 nsec. Under free-lasing conditions, the efficiency was 1.25% and the output radiation energy 5 J. The radiation parameters were strongly influenced by the Stark splitting of the /sup 4/I/sub 11/2/ and /sup 4/I/sub 13/2/ active levels.
