Abstract: A description is given of a method for growing chromium-activated yttrium aluminum garnet crystals. The results are reported of an investigation of the influence of chromium concentration from 0.01 to 1.0 wt.% on the absorption and luminescence spectra of garnet crystals. Broadening and short-wavelength shift of the R lines are attributed to the expansion of the garnet lattice with increasing chromium concentration. The intensities of the wide Y and U bands and of R lines are linear functions of the chromium concentration. An optical method is suggested for the determination of the chromium concentration in Y₃Al₅O₁₂:Cr³⁺ crystals.
