KTA Crystal
Potassium Titanyle Arsenate (KTiOAsO4), ko KTA crystal, kyakkyawan lu'ulu'u ne na gani mara kyau don aikace-aikacen Oscillation na gani na gani (OPO).Yana da mafi kyawun hanyoyin gani marasa layi da na gani na lantarki, rage yawan sha a cikin yanki na 2.0-5.0 µm, faffadan angular da yanayin zafi, ƙananan madaidaicin dielectric.Kuma ƙananan halayen ion ɗin sa yana haifar da mafi girman lalacewa idan aka kwatanta da KTP.
Ana amfani da KTA akai-akai azaman matsakaicin ribar OPO / OPA don fitarwa a cikin kewayon 3µm da kuma OPO crystal don fitar da lafiyar ido a matsakaicin matsakaicin ƙarfi.
Siffa:
