Simultaneous lasing of both Ho3+ and Nd3+ in the same crystal of yttrium aluminum garnet (YAG) is reported. The crystal was doped with 10% Ho3+ and 1% Nd3+ ions. Lasing occurred at 2.940 and 3.011 μm due to Ho3+ ion transitions and at 1.064 μm due to a Nd3+ transition. Appropriate mirrors produced simultaneous lasing at 1.064 and 1.339 μm due to Nd3+ ion transitions. The fluorescent lifetimes of both the Nd3+ 4F3/2 and Ho3+ 5I7 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.
