摘要：

914　nm　wavelength　in-band　pumping　of　Nd:YVO4　reduces　crystal　thermal　load　and　end-surface　thermal　stress,　then　the　performance　of　Nd:YVO4　regenerative　amplifier　is　enhanced　at　high　repetition　rate.　The　influence　of　high-voltage-duration　applied　to　Pockel-cell　on　Nd:YVO4　regenerative　amplifier　with　output　pulse　stability　of　100　kHz　is　investigated　in　detail.　When　68　W　pumping　power　at　914　nm　center　wavelength　is　absorbed　by　the　Nd:YVO4　crystal　and　appropriated　high-voltage-duration　is　applied　to　Pockel-cell,　the　Nd:YVO4　regenerative　amplifier　that　produces　stable　21.2　W　average　power　at　100　kHz　repetition　rate　is　seeded　by　a　low　power　of　1　nJ　and　5.7　ps　duration　semiconductor　saturable　absorber　mirror　(SESAM)　mode-locked　Nd:YVO4　laser　with　repetition　rate　of　42.7　MHz.
