Absorption and emission measurement were made on ruby (Cr:Al2O3) crystal with 0.5 wt. %). The results for optical absorption spectra of Cr3+:Al2O3 single crystal are shows two strong absorption bands at 408 nm and 558 nm in the range spectrum between 390 nm and 600 nm, meanwhile three broad absorption bands at 205 nm, 227 nm and 255 nm in range spectrum between 190 nm and 370 nm. The emission band when excited by UV light at 205 nm, 227 nm and 255 nm were detected and centered at 321 nm. The emission band by the excitation of 408 nm was found at 465 nm, 671 nm, 692 nm and 710 nm. Meanwhile, the emission band under the excitation of blue light at 490 nm was detected at 671 nm, 692 nm and 710 nm. The emission band at 671 nm, 688 nm, 695 nm and 710 nm were detected from excitation by green light with wavelength at 532 nm and 558 nm. © 2019 Published under licence by IOP Publishing Ltd.
