By　using　a　reflection　type　of　topological　insulator　Bi2Te3　as　saturable　absorber　that　was　prepared　by　a　hydrothermal　intercalation/exfoliation　method,　we　have　demonstrated　the　stable　Q-switched　mode-locked　operation　of　Nd:YVO4　solid-state　laser.　Its　maximum　output　power　can　reach　up　to　247　mW　with　respect　to　the　absorbed　pump　power　of　6.39　W.　To　the　best　of　our　knowledge,　this　is　the　first　report　for　passively　Q-switched　mode-locking　Nd:YVO4　solid-state　laser　at　1-mu　m　wavelength　using　a　topological　insulator　Bi2Te3　as　saturable　absorber.　In　the　experiment,　we　have　also　observed　the　stable　Q-switched　operation　with　pulse　width　as　short　as　2　mu　s,　output　power　183　mW,　and　repetition　rate　up　to　151.5　kHz.
