| Abstract: | The Cr3+:KAl(MoO4)2 single crystal was grown by top seeding solution growth method (TSSG). Based on the absorption and emission spectra, the crystal field strength Dq, the Racah parameters B and C, the effective phonon energy ?ω and the Huang-Rhys factor S were calculated: Dq = 1494.8 cm− 1, B = 585.5 cm− 1 and C = 3049 cm− 1, ?ω = 373.8 cm− 1 and the Huang-Rhys factor S = 3.74, respectively. The value Dq/B = 2.55 indicates that Cr3+ ion occupies the strong crystal field site in KAl(MoO4)2 crystal. A comparison of crystal field parameters for Cr3+:KAl(MoO4)2 with other Cr3+-doped crystals was presented. The results of spectral measurement show that Cr3+:KAl(MoO4)2 may be a potential candidate for broadband laser applications. |
