Cylindrical　vector　beams　(CVBs)　represent　a　prominent　application　mode　characterized　by　cylindrically　symmetric　intensity　distributions.　In　particular,　vectorial　vortex　beams　with　spatially　continuously　varying　polarization　states　have　garnered　significant　research　attention　due　to　their　unique　ability　to　manipulate　matter　through　innovative　interaction　mechanisms.　To　generate　switchable　scalar　orbital　angular　momentum　(OAM)　and　CVB　lasers　using　integrated　devices,　metasurfaces　with　liquid　crystals　(LCs)　have　emerged　as　a　promising　integrated　platform　with　substantial　implications　for　nanophotonics　and　optical　field　modulation.　The　device　enables　precise　control　of　scalar　vortex　beams　using　silicon　antennas　in　a　horizontal　polarization　state.　Simultaneously,　the　orientation　of　LC　molecules　can　be　dynamically　switched　on　or　off　to　form　OAM　beams　in　the　vertical　polarization　state,　leveraging　the　polarization-sensitive　modulation　characteristics　of　nematic　LCs.　This　approach　facilitates　two　distinct　operational　modes.　First,　compensating　for　the　horizontal　polarization　phase　of　the　silicon　antenna　to　produce　a　scalar　linearly　polarized　laser,　and　second,　generating　vertically　polarized　vortex　light　to　create　a　cylindrical　vector　laser.　Our　study　demonstrates　a　practical　methodology　for　harnessing　switchable　scalar　OAM　and　CVB　lasers　with　high-speed　responsiveness　and　exceptional　spatial　mode　diversity.　The　proposed　technique　holds　considerable　potential　for　advanced　applications　in　3D　optical　trapping,　communications,　holography　and　related　interdisciplinary　fields.
