摘要：

A　micro　processing　used　LD　end-pumped　Nd:YVO4　all　solid-state　picosecond　pulse　laser　was　demonstrated　under　the　semiconductor　saturable　absorption　mirror(SESAM)　mode-locking　technology　and　regeneration　amplifier　technology,　by　using　BBO　crystal　as　electro-optic　crystal　and　diode-side-pumped　Nd:YAG.　1064nm　laser　was　obtained　with　1.47mJ　single　pulse　energy,　15ps　pulse　width　at　1　kHz　repetition　rate　and　the　pulse　energy　fluctuation　was　less　than　0.6%　in　3　hours　operation.　Finally,　through　the　galvanometric　we　got　the　beam　focused,　realizing　the　steel　plate　processing　which　thickness　was　0.5mm　and　the　aperture　radius　was　25.5　mu　m.
