Simultaneous lasing of both Ho/sup 3 +/ and Nd/sup 3 +/ in the same crystal of yttrium aluminum garnet (YAG) is reported. The crystal was doped with 10% Ho/sup 3 +/ and 1% Nd/sup 3 +/ ions. Lasing occurred at 2.940 and 3.011 ..mu..m due to Ho/sup 3 +/ ion transitions and at 1.064 ..mu..m due to a Nd/sup 3 +/ transition. Appropriate mirrors produced simultaneous lasing at 1.064 and 1.339 ..mu..m due to Nd/sup 3 +/ ion transitions. The fluorescent lifetimes of both the Nd/sup 3 +/ /sup 4/F/sub 3//sub ///sub 2/ and Ho/sup 3 +/ /sup 5/I/sub 7/ states were significantly lower in the doubly doped material than in Nd:YAG and Ho:YAG. This indicates very strong ion-ion interactions in the (Ho, Nd):YAG crystal.
