By　using　double-mixed　crystal　Nd:Lu0.15Y0.85VO4　as　laser　medium,　a　diode-pumped　doubly　Q-switched　and　mode-locked　(QML)　Nd:Lu0.15Y0.85VO4　laser　with　acousto-optic　(AO)　modulator　and　central　semiconductor　saturable　absorption　mirror　(SESAM)　is　realized　for　the　first　time.　The　Q-switched　envelope　modulation　depth　is　nearly　100%.The　average　output　power　and　the　pulse　width　of　the　Q-switched　envelope　etc.　for　different　AO　modulator　repetition　rates　have　been　measured.　The　experimental　result　show　that　Nd:Lu0.15Y0.85VO4　crystal　is　an　excellent　laser　medium　for　doubly　QML　lasers.
