Two titanium-doped perovskites, EuAlO{sub 3} and GdAlO{sub 3}, have been grown by laser-heated pedestal growth as potential visible--near-infrared lasers. The absorption spectra of EuAlO{sub 3}:Ti and the lack of Ti{sup 3+} fluorescence from this material indicate the dominance of a charge-transfer transition between titanium and europium. The spectra of GdAlO{sub 3}:Ti in the visible region are consistent with Ti{sup 3+} in an octahedral field. The absence of the charge-transfer transitions in the spectra of GdAlO{sub 3}:Ti is due to the third ionization potential of Gd's being approximately 4 eV smaller than that of Eu. GdAlO{sub 3}:Ti has potential as a tunable-laser material with a center wavelength of 610 nm.
