Abstract：

A　laser　diode　(LD)　pumped　Er3+,　Yb3+:glass/Co2+:MgAl2O4　composite　material　passively　Q-switched　miniature　laser　is　reported　for　laser　ranging.　Er3+,　Yb3+　co-doped　phosphate　glass　is　used　as　the　gain　medium,　and　Co2+:MgAl2O4　is　used　as　a　Q-switched　laser　saturable　crystal.　The　gain　medium　and　a　Q-switched　rystal　are　compounded.　The　composite　material　can　reduce　the　temperature　gradient　inside　the　gain　medium,　increase　the　thermal　focal　length　and　the　mode　volume,　and　improve　the　laser　beam　quality.　In　addition,　the　composite　material　reduces　the　cavity　loss,　the　density　of　the　particles　in　the　cavity　increases,　the　pulse　width　becomes　narrower,　and　the　output　energy　increases,　so　that　the　laser　performance　is　improved.　Eventually,　we　get　a　wavelength　is　1　535　nm　a　with　repetition　frequency　of　10　Hz.　The　center　wavelength　of　pump　source　is　940　nm.　The　single　pulse　energy　is　210　μJ,　and　pulse　width　is　2.8　ns.The　peak　power　is　higher　than　70　kW,　and　beam　quality　of　M2　is　1.2.　©　2017,　Science　Press　in　China.　All　right　reserved.
