A　passively-Q-switched　Yb:Lu1-x-yYxLayVO4　laser　based　on　a　two-dimension　(2D)　molybdenum　ditelluride　(MoTe2)　saturable　absorber　(SA)　is　reported　for　the　first　time　to　the　best　of　our　knowledge.　High　quality　few　layered　2D　MoTe2　nanosheets　were　fabricated　by　liquid　phase　exfoliation　(LPE)　method　and　used　as　the　SA,　whose　saturable　absorption　properties　around　1.0　mu　m　were　characterized　with　a　saturation　fluence　of　3.02　mu　J/cm(2)　and　a　modulation　depth　of　8.3%.　In　the　passively　Q-switched　laser　operation,　the　shortest　pulse　width　of　500　ns　was　obtained　with　an　average　output　power　of　0.33　W　at　a　pulse　repetition　rate　of　117　kHz,　corresponding　to　the　maximum　single　pulse　energy　of　2.8　mu　J　and　the　peak　power　of　5.6　W.
