摘要：

The　volume　Bragg　grating　(VBG)　recorded　in　photo-thermo-refractive　(PTR)　glass　is　used　as　longitudinal　mode　selection　element,　and　use　the　narrow　filter　which　consists　of　transmitting　and　reflecting　gratings　to　select　longitudinal　mode.　We　have　obtained　1053　nm　single　frequency　mode　with　100%　single　longitudinal　mode　rate,　2　mJ　pulse　energy　in　Nd:YLF　laser.　The　experimental　results　show　that　the　volume　Bragg　gratings　work　as　both　mode　selector　and　output　coupler,　therefore　simplify　the　structure　of　the　cavity　structure　and　improve　the　anti-interference　ability.　The　laser　also　has　the　potential　of　high-power　output.
