Crystal KDP & DKDP
KDP (KH2PO4 ) ati DKDP / KD * P (KD2PO4 ) wa ninu awọn ohun elo NLO ti iṣowo ti a lo pupọ julọ. Pẹlu gbigbe UV to dara, ilẹ bibajẹ giga, ati birefringence giga, awọn ohun elo yii ni a maa n lo fun ilọpo meji, irin-ajo ati didamu ti Nd: YAG laser.
Pẹlu olùsọdipúpọ EO giga, awọn kirisita KDP ati DKDP ni a tun lo ni ibigbogbo lati ṣe awọn sẹẹli Pockels fun eto laser, bii Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, bbl Paapaa botilẹjẹpe DKDP pẹlu itujade giga jẹ lilo pupọ diẹ sii, KDP ati DKDP mejeeji le ṣe ipele ibaramu alakoso ti Iru I ati Iru II fun SHG ati THG ti 1064nm Nd: YAG laser. A ṣeduro KDP fun FGH ti Nd: YAG laser (266nm).
Gẹgẹbi ọkan ninu awọn olupese KDP / DKDP pataki (olupese orisun) ni gbogbo ọja ti kariaye, WISOPTIC ni agbara giga ti yiyan ohun elo, ṣiṣe (didi, ti a bo, fifi goolu, ati be be lo). WISOPTIC jẹrisi idiyele idiyele, iṣelọpọ ibi-ọja, ifijiṣẹ iyara ati akoko iṣeduro gigun ti awọn ohun elo wọnyi.
