Spectroscopic properties of Pr3+:KY(MoO4)2 crystal as a visible laser gain medium

A Pr3+-doped KY(MoO4)2 single crystal was grown by the Czochralski method. The polarized absorption and fluorescence spectra of the Pr3+:KY(MoO4)2 crystal were measured at room temperature. The stimulated emission cross-sections for the transitions from the 3P0 multiplet were estimated from the fluorescence spectra. The fluorescence lifetime of the 3P0 multiplet was estimated from the fluorescence decay curve at room temperature. The analysis of spectral properties shows that the Pr3+:KY(MoO4)2 crystal is a promising gain medium for visible lasers.
