摘要：

The　linewidth　of　KBe2BO3F2　crystal　optical　parametric　oscillator　(KBBF-OPO)　has　investigated　using　theoretical　analysis　and　simulation　in　type-I　phase　matching　(PM).　The　Linwidth　ranges　of　81-250nm　with　the　spontaneous　parametric　emission,　230-690nm　with　the　divergence　angle　of　pumping　beam,　and　19-96nm　the　linewidth　of　signal　light　are　obtained,　respectively.　It　is　shown　that　the　linewidth　of　signal　is　very　narrow　far　away　from　the　degeneracy　point　and　the　linewidth　increased　near　the　degeneracy　point　and　given　the　results　that　KBBF-OPO　has　smaller　linewidths　than　that　of　CLBO-OPO　in　type　I.　The　divergence　angle　of　pumping　beam　and　the　off-axis　of　pumping　beam　influenced　the　signal　linewidth　more　seriously　than　other　factors　do.　These　results　are　important　for　compression　the　linewidth　of　OPO　signal　and　useful　for　construction　high　power　KBBF-OPO　laser.
