Simultaneous lasing of both Er3+ and Nd3+ ions in yttrium aluminum garnet is reported. The crystal was doped with 15% Er3+ and 1% Nd3+ ions. The Er3+ ions lased at 2.94 μm and the Nd3+ ions in a broadband from 1.01 to 1.15 μm with a strong peak at 1.064 μm. Significant ion-ion interaction is suggested by the drastically altered fluorescent lifetimes and unusual lasing properties.
