Polarized　fluorescence　spectra　and　laser　emission　of　π-　and　σ-polarization　were　investigated　with　a　Nd:　Lu0.5Y0.5VO4　mixed　crystal.　A　polarizing　beam　splitting　cube　was　proposed　for　active　selection　of　oscillating　polarization.　At　a　pump　power　of　12.4 W,　5.72 W　single　wavelength　laser　at　1065.1 nm　and　3.55 W　dual-wavelength　laser　at　1064.9　and　1067.3 nm　were　obtained　for　π-　and　σ-polarization,　respectively.　The　wavelength　at　1341 nm　for　both　polarization　output　were　also　studied.　The　broader　fluorescence　spectra　with　σ-polarization　will　be　excellent　in　ultra-short　pulses　production.　©　2016　Elsevier　B.V.
