KDP & DKDP Crystal
KDP (KH2PO4 ) na DKDP / KD * P (KD2PO4 ) so n’ihe ndị NLO na-azụkarị ahịa. Site na ezigbo nnyefe UV, ọnụ ụzọ mmebi emebi, yana mbibi dị elu, a na-ejikarị ihe ndị a emegharị ọnụ, njem na ịgbagha nke Nd: YAG laser.
N’akọtara ọnụ nke EO dị elu, a na-ejikwa KDP na DKDP kristal ime ka mkpụrụ ndụ Pockels maka sistemụ laser, dịka Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, wdg. KDP na DKDP ha abụọ nwere ike ịme mmekorita nke ụdị I na ụdị II maka SHG na THG nke 1064nm Nd: YAG laser. Anyị na-akwado KDP maka FGH nke Nd: YAG laser (266nm).
Dịka otu n’ime ndị na - eweta KDP / DKDP bụ isi (onye na - emepụta ihe) na mpaghara ụwa dum, WISOPTIC nwere ikike nke nhọrọ ihe, nhazi (ịmịcha mkpuchi, mkpuchi, ịbịanye ọla edo, wdg). WISOPTIC na-akwado ọnụego ezi uche dị na ya, mmepụta oke, nnyefe ngwa ngwa na ogologo oge nke ihe ndị a.
Kpọtụrụ anyị maka usoro kachasị mma maka ngwa kristal KDP / DKDP.
