Abstract：

70%　deuterated　DKDP　crystals　are　used　as　type-II　third　harmonic　generator(THG)　optics　in　inertial　confinement　fusion(ICF)　systems,　while　DKDP　crystals　with　70%　deuterium　content　are　difficult　to　grow　and　expensive.　Therefore,　it　is　necessary　to　select　DKDP　crystals　with　low　deuterium　content　and　performance　meeting　ICF　systems　as　type　II　third　harmonic　generator　optics　crystals.　A　about　35%　DKDP　crystal　was　grown　by　a　rapid　horizontal　growth　method,　which　was　cut　at　the　type　II　THG　direction,　laser　induced　damage　threshold　and　transverse　stimulated　Raman　scattering　were　measured　and　compared　with　70%　DKDP　crystal.　The　experimental　results　show　that　the　laser　induced　damage　of　35%　DKDP　crystal　was　about　1.8　times　higher　than　that　of　70%　DKDP　crystal,　while　the　Raman　scattering　peak　intensity　of　881.7　cm-1,　35%　DKDP　crystal　was　about　23%　higher　than　that　of　70%　DKDP　crystal,　and　transverse　stimulated　Raman　scattering　of　70%DKDP　crystal　was　smaller　than　that　of　35%　DKDP.　©　2019,　Chinese　Ceramic　Society.　All　right　reserved.
