摘要：

A　mode-locked　radially　polarized　laser　is　generated　based　on　the　difference　of　thermal　focal　length　in　side-pumped　Nd:　YAG　and　the　condition　of　mode-locking　by　the　semiconductor　saturable　absorption　mirror　(SESAM).　The　spot　size　of　radial　polarization　and　azimuthal　polarization　with　different　pumping　currents,　and　the　parameters　of　the　LD　side-pumped　Nd:YAG　four-mirror-folded　passively　mode-locked　cavity　are　analyzed.　The　maximum　output　power　of　13　W　with　the　frequency　of　59　MHz　and　the　wavelength　of　1064　nm　is　acquired.　We　demonstrate　that　the　purity　of　the　radially　polarized　beam　is　more　than　92%.
