By　using　both　a　single-walled　carbon　nanotube　saturable　absorber　(SWCNT-SA)　and　an　acousto-optic　(AO)　modulator,　a　dual-loss-modulated　intra-cavity　frequency-doubled　Q-switched　and　mode-locked　(QML)　Nd:Lu0.15Y　0.85VO4/KTP　(KTiOPO4)　green　laser　was　demonstrated　for　the　first　time.　The　QML　green　laser　characteristics　such　as　the　pulse　width　and　single-pulse　energy　have　been　measured　for　different　modulation　frequencies　of　the　AO　modulator　(fp).　In　particular,　in　comparison　with　the　solely　passively　QML　green　laser　with　an　SWCNT-SA,　the　dual-loss-modulated　QML　green　laser　can　generate　a　more　stable　pulse　train,　a　shorter　pulse　width　of　the　Q-switched　envelope,　a　greater　pulse　energy　and　a　higher　average　peak　power.　For　the　dual-loss-modulated　QML　green　laser,　at　a　pump　power　of　7.9W　and　a　repetition　rate　of　10kHz,　the　pulse　width　and　the　pulse　energy　of　the　Q-switch　envelope　and　the　average　peak　power　of　the　QML　green　laser　are　50ns,　20.34μJ　and　15.5kW,　respectively,　corresponding　to　a　pulse　width　compression　of　77%,　a　pulse　energy　improvement　factor　of　six　times　and　a　QML　peak　power　increase　factor　of　16　times　when　compared　with　those　for　the　solely　passively　QML　green　laser.　The　experimental　results　show　that　the　dual-loss　modulation　is　an　efficient　method　for　the　generation　of　a　stable　QML　green　laser　with　an　SWCNT-SA.　©　2011　IOP　Publishing　Ltd.
