Polarized　fluorescence　spectra　and　laser　emission　of　pi-　and　sigma-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　pi-　and　sigma-polarization,　respectively.　The　wavelength　at　1341　nm　for　both　polarization　output　were　also　studied.　The　broader　fluorescence　spectra　with　sigma-polarization　will　be　excellent　in　ultra-short　pulses　production.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
