摘要：

Yb:KGW　laser　material　is　well　suited　to　build　diode-pumped　pulse　lasers　in　watt　region　because　of　its　broad　gain　bandwidth　of　24　nm,　large　emission　cross　section　of　2.8×10-20　cm2　and　good　thermal　conductivity　of　3.3　W/(m·K).　A　passively　Q-switched　Yb:KGW　laser　is　obtained　using　a　transmission-type　topological　insulator　Bi2Se3　as　a　saturable　absorber.　The　achieved　maximum　pulse　energy　is　4.7　mJ　and　the　peak　power　is　3.13　W　for　a　pulse　duration　of　1.5　ms.　©,　2015,　Science　Press.　All　right　reserved.
