KDP me te DKDP Crystal
KDP (KH2PO4 ) me DKDP / KD * P (KD2PO4 ) kei roto i nga taonga NDR tino whai mana nui. Ma te pai o te whakawhitinga UV, te paepae kino kino, me te kaha nui o te waa, ka whakamahia enei taonga mo te takirua, te haerenga me te koretake o te Nd: YAG laser.
Ma te nui o te mahi EO, kei te whakamahia whānuitia te KDP me nga tioata DKDP ki te hanga pallels mo nga punaha laser, penei i a Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, me etahi atu ahakoa ko DKDP me te deuteration tiketike e whakamahia nuitia ana. Ka taea e te KDP me te DKDP te whakarite i te momo momo I me te II te momo mo te SHG me te THG o te 1064nm Nd: YAG laser. Ka tūtohu matou ki te KDP mo te FGH o Nd: YAG laser (266nm).
I te mea ko tetahi o nga kaiwhakarato KDP / DKDP (kaihanga rauemi) i te maakete o te ao katoa, ko te WISOPTIC te kaha o te kowhiringa o nga taonga, te tukatuka (paninga, paninga, pania koura, aha). E whakaū ana te WISOPTIC i te utu tika, te hanga papatipu, te tere tere me te waa taurangi o enei taonga
Whakauru mai ki a maatau mo te otinga pai mo to tono ki nga tioata KDP / DKDP.
