The spectroscopic investigation of the highly transparent rare earth (Pr3+, Nd3+, Ho3+, Er3+, Tm3+, Yb3+) doped Sc2O3
ceramics produced by the solid-state synthesis technique indicate that these materials could substitute the single crystals
in construction of solid-state lasers. These studies indicate also that the rare earth doped transparent ceramics could
extend considerably the variety and performances (new active systems, wavelength ranges or emission schemes) of these
lasers.
