Absorption, fluorescence, and excitation spectra of a single crystal of Ba2MgGe2O7: Nd3+ were investigated. The lifetime of the 4F3/2 state of the neodymium ion is 450 μsec at 300°K. The width of the strongest fluorescence line at 1.054 μ is 35 and 10 Å at 300° and 80°K, respectively. Laser action was achieved at 1.05444 μ at room temperature.
