A preliminary non-stimulated study of the laser host combination Gd2 - xTbxMoO43 is made. The host material, gadolinium molybdate GMO, is a ferroelectricferroelastic crystal. An investigation of temperature and external electric field affects on the absorption and fluorescence of the crystal did not produce any unusual results. The terbium ion, Tb3, peak cross section in GMO for the 5D sub 4 to 7F sub 5 transition is 10 x 10 to the minus twenty first power sq. cm. at 300K. The wavelength of this four level laser transition is 543 nm.
