Abstract

The absorption and fluorescence spectra of the Cr3+: LiNbO3 crystal was taken with a spectrophotometer and laser-indused fluorescence technique respectively. Following results were obtained: crystal field parameter Dq/B - 2.49, energy difference of 4T2 and -E states = 114cm-1, emission cross-section of 4T2-4A2 transition σe=6.58x10-20cm2; and fluorescence lifelime of 4T2-4A2 transition Tf=2μs. The energy level structure of Cr3+ in LiNbO3 crystals were also explined theoretically.
