This　manuscript　designs　a　compact　LD　single　emitter　end-pumped　1319　nm　vortex　laser.　In　order　to　compress　the　divergence　angle　and　meet　the　requirements　of　compact　design,　a　fast-axis　and　slow-axis　integrated　collimating　lens　was　designed,　with　X　and　Y　divergence　angles　of　1.87°　and　0.99°　after　collimation.　On　this　basis,　a　hollow　pump　beam　was　obtained　by　using　a　plano-convex　lens　and　an　axicon-lens.　By　simulating　the　pump　beam　at　different　angles　of　the　axicon-lens,　an　ideal　hollow　pump　light　was　obtained　by　using　an　axicon-lens　with　a　cone　angle　of　20°.　A　bonded　crystal　of　Nd:　YAG　and　V:　YAG　was　used,　which　utilizes　selective　dielectric　coatings　on　the　crystal　end　facets　to　suppress　laser　oscillation　at　1064　nm　and　1338　nm,　and　1319　nm　laser　can　be　obtained.　Subsequently,　the　heat　dissipation　structure　for　the　pump　module　and　the　bonded　crystal　module　was　designed　and　the　feasibility　of　the　heat　dissipation　model　was　verified　through　ANSYS　simulation.　©　2023　SPIE　·　0277-786X.
