摘要：

The　laser　uses　one　reflecting　volume　Bragg　grating　(RBG)　as　output　mirrort,　the　gain　medium　is　Nd:　YVO4　crystal　and　it　is　end　pumped　by　a　fiber-coupled　quasi-continuous　semiconductor　laser.　The　electro-optically　(E-O)　Q-switching　way　is　used　to　get　single　longitudinal　mode　laser　with　narrow　pulse　width.　When　the　optical　cavity　length　is　38　mm　with　the　repetition　frequency　from　5　Hz　to　150　Hz,　a　stable　single　longitudinal　mode　laser　output　with　pulse　width　of　1.92　ns　and　the　single　pulse　energy　of　0.38　mJ　is　obtained.
