Hoʻohālikelike ʻia meLN maʻamauaniani(CLN)me ka haku mele like, ka nele o ka lithium ma kahi kokoke-stoichiometricLNaniani(SLN)alakaʻi i ka emi nui o ka lattice defects, a nui nā waiwai e hoʻololi e like me ia.Aia ka papa ma lalo nei i ka mea nuiokoa owaiwai kino.

Hoʻohālikelike ʻia meCLNme ka haku mele like, ka hapa nui o na waiwai oSLNua hoʻomaikaʻi ʻia i nā pae like ʻole.ʻO ka optimization koʻikoʻi nui e pili ana:

(1) Whether photorefractive doping, anti-photorefractive doping a i ole laser-activated ion doping,Loaʻa iā SLNʻoi aku ka paʻakikī o ka hoʻoponopono hana.Kong et al.'ike 'ia i ka hiki 'ana o [Li]/[Nb] i 0.995 a he 1.0mol% ka nui o ka magnesium, ke kū'ē photorefractive o kaSLNhiki i ka 26 MW/cm2, ʻo ia ka 6 kauoha o ka nui ma mua o kaCLNme ka haku mele like.ʻO ka doping photorefractive a me ka laser-activated ion doping kekahi mau hopena like.

(2) E like me ka helu o nā hemahema lattice i lokoSLNke emi nui nei ke aniani, pela no ka ikaika o ke kahua coercivity o ke aniani, a ke emi iho nei ka volta e pono ai no ka hoohuli polarization mai kahi o 21 kV/mm.(o CLN)ma kahi o 5 kV/mm, he mea maikaʻi loa ia no ka hoʻomākaukau ʻana i nā mea hana superlattice.Eia kekahi, ka hoʻolālā domain uila oSLNʻoi aku ka maʻamau a ʻoi aku ka maʻalahi o nā paia domain.

(3)Nui nā photoelectricwaiwai oSLNua hoʻomaikaʻi nui ʻia, e like me ka electro-optic coefficientr61hoʻonui ʻia e 63%, hoʻonui ʻia ka coefficient nonlinear e 22%, hoʻonui ʻia ka birefringence kristal e 43% (lōʻihi hawewe 632.8 nm), hoʻololi polū.o UVlihi absorption, etc.
