摘要：

A　miniature　diode　pumped　passively　Q-switched　Er3+　and　Yb3+　co-doped　phosphate　glass　laser　is　reported.　The　center　wavelength　of　pump　source　is　940　nm.　A　Co2+:MgAl2O4　crystal　is　used　as　a　saturable　absorber.　When　the　pump　energy　is　14　mJ,　stable　Q-switched　pulses　are　obtained　at　repetition　frequency　of　10　Hz　and　pump　pulse　width　of　5　ms.　The　output　pulse　energy　of　laser　is　480　μJ　and　pulse　width　is　5　ns.　The　wavelength　of　laser　is　1535　nm.　The　peak　power　is　higher　than　20　kW　and　beam　quality　is　1.2.
