Continuous　wave　and　passively　Q-switched　laser　operation　with　a　mixed　c-cut　Nd:Gd0.33Lu0.33Y0.33VO4　crystal　at　1.34　mu　m　has　been　realized　for　the　first　time　as　far　as　we　know.　The　largest　output　power　of　the　continuous　wave　was　1.1　W　for　the　output　mirror　01　5%　transmission,　with　the　optical　conversion　efficiency　and　the　slope　efficiency　being　15%　and　17.2%,　respectively.　The　passive　loss　and　the　stimulated　emission　cross-section　of　the　Nd:Gd0.33Lu0.33Y0.33VO4　crystal　were　found　to　be　0.6%　and　0.47　x　10(-19)　cm(2).　The　thermal　lens　effect　that　weakened　the　laser　performance　has　also　been　measured.　For　passively　Q-switched　operation,　the　shortest　pulse　duration　of　26　ns,　the　highest　peak　power　of　1.8　kW,　along　with　the　pulse　energy　as　large　as　47　mu　j,　were　obtained　using　V:YAG　as　Q-switch.　The　experimental　results　have　shown　that　the　passively　Q-switched　Nd:Gd0.33Lu0.33Y0.33VO4　laser　can　generate　pulses　with　larger　pulse　energy　and　higher　peak　power　in　comparison　with　the　passively　Q-switched　Nd:GdYVO4　lasers.　(C)　2011　Elsevier　B.V.　All　rights　reserved.
