摘要：

1319nm　lasers　have　important　applications　in　optical　communication,　LIDAR,　laser　display,　laser　medical,　etc.　In　applications　such　as　LIDAR,　reliable　operation　over　a　wide　temperature　range　is　a　key　indicator　of　the　laser.　Vertical　cavity　surface　emitting　lasers　are　new　pump　sources　for　all-solid-state　lasers　because　of　their　narrow　linewidth,　small　temperature　drift　coefficient,　and　two-dimensional　expansion.　In　this　paper,　we　report　an　808nm　VCSEL　end-pumped　Nd:YAG　1319nm　Q-switched　laser　that　can　operate　stably　over　a　wide　temperature　range,　The　whole　laser　is　dissipated　by　natural　conduction　cooling,　the　VCSEL　array　is　collimated　by　a　two-dimensional　microlens　array　for　beam　shaping,　and　Nd:YAG　is　used　as　the　dielectric　crystal　to　obtain　a　1319nm　laser　output　with　a　maximum　single　pulse　energy　of　2.8mJ　and　a　beam　quality　of　M2　©　2023　SPIE.
