Strontium lanthanum hexa-aluminates crystals (ASL) doped with Sm3+ with formula Sr1-xSmyLax-yMgxAl12-xO19 are investigated for lasers operating in visible spectral range. The crystal with compositional parameters x = 0.2 and y = 0.05 have been grown by the Czochralski pulling technique. High resolution optical absorption and emission spectra at 10K and room temperature were recorded. Preliminary investigations of spectroscopic properties of Sm3+ doped ASL crystal were carried out.
