I-KDP ne-DKDP Crystal
I-KDP (KH2I-PO4 ) kanye ne-DKDP / KD * P (KD2I-PO4 ) ziphakathi kwezinto ezisetshenziswa kakhulu ezisetshenziselwa ukuthengisa zeNLO. Ngokudluliselwa okuhle kwe-UV, umkhawulo omkhulu wokulimala, kanye ne-birefringence ephezulu, lezi zinto ezibonakalayo zivame ukusetshenziselwa ukuphindeka kabili, ukuphindaphinda kathathu kwe-Nd: YAG laser.
Ngokuqina okuphezulu kwe-EO, amakristalu e-KDP ne-DKDP asetshenziswa kabanzi ukwenza amaseli we-Pockels wohlelo lwe-laser, njengo-Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, njll. Noma kusetshenziswa kakhulu i-DKDP I-KDP ne-DKDP zombili zingenza isigaba sokuqhathanisa sohlobo I bese sithayipha II i-SHG ne-THG ye-1064nm Nd: YAG laser. Sincoma i-KDP ye-FGH yeNd: YAG laser (266nm).
Njengomunye wabahlinzeki abakhulu be-KDP / DKDP (umenzi womthombo) kuyo yonke imakethe yamazwe omhlaba, i-WISOPTIC inamandla aphezulu ekukhetheni izinto ezibonakalayo, ukucubungula (polishing, coating, plating gold, njll). I-WISOPTIC iqinisekisa intengo enengqondo, ukukhiqizwa kwesisindo, ukulethwa okusheshayo nesikhathi eside sesiqinisekiso salezi zinto zokwenziwa.
Xhumana nathi ngesisombululo esihle kakhulu sohlelo lwakho lokusebenzisa amakristalu weKDP / DKDP.
