Abstract
Under reducing conditions, single crystal of LiYF4 doped with 762 ppm of U3+ were obtained. Absorption and fluorescence spectra of this syst em are presented as well as the energy level scheme of the lasing tran sition. Oscillator strength and laser cross section between Stark leve ls of the I-4(11/2) --> I-4(9/2) transition are calculated
