Self-Q-switched Cr,Nd:ReVO4 (Re=Gd, Y) crystal lasers

Abstract

Self-Q-switched Cr,Nd:ReVO4 (Re=Gd, Y) crystallasers are demonstrated. The spectroscopic and self-Q-switched laser properties of Cr,Nd:ReVO4 arestudied. Polarized absorption spectra weremeasured at room temperature, which showed thatthe absorption bands display polarization characterand an absorption band of Cr5+ ions at 1110 nmenables the crystals to be self-Q-switched lasermaterials. The maximum pulse energy are achievedto be 1.12 μJ with Re=Gd , and the shortest pulsewidth is 85.8 ns with Re=Y. The results show thatCr,Nd:ReVO4 crystals are new potential self-Qswitchedlaser materials.
