| Abstract: | This paper reports polarized spectral properties and energy levels of Cr3+ in KAl(MoO4)2 crystal. The absorption and emission cross sections are estimated as 3.72×10-20 cm2 at 669 nm and 2.74×10-20 cm-2 at 823 nm for σ-polarization, respectively. The energy levels of Cr3+ ion in KAl(MoO4)2 crystal were calculated based on the Tanabe-Sugano theory. It is suggested that Cr3+ ions occupy at an intermediate crystal field site in Cr3+:KAl(MoO4)2. |
