摘要：

Mode　locked　and　cavity　dumping　techniques　are　comtined　to　get　picosecond　pulse　with　high　energy　at　high　repetition　rate.　The　mechanism　and　physical　image　of　cavity-dumping　mode-locked　laser　are　analyzed　and　factors　which　affect　the　dumping　efficiency　of　cavity-dumping　laser　are　studied.　Cavity-dumping　mode-locked　laser　at　repetition　rate　of　10　kHz　can　be　realized　with　the　help　of　Nd:YVO4　SESAM　mode-locking　and　a　BBO　modulator　placed　in　cavity.　When　pump　power　is　14.1　W,　pulses　with　energy　of　6.5　μJ　are　obtained,　and　the　pulse　width　is　about　10.4　ps.　This　kind　of　laser　will　have　good　prospects　for　development　because　high　energy　pulses　can　be　obtained　directly　from　mode-locked　oscillator.
